     BACKGROUND 
     In computing, a server is a piece of computer hardware or software (computer program) that provides functionality for other programs or devices, called “clients.” This architecture is called the client-server model. Servers can provide various functionalities, often called “services,” such as sharing data or resources among multiple clients, or performing computation for a client. A single server can serve multiple clients, and a single client can use multiple servers. A client process may run on the same device or may connect over a network to a server on a different device.

     DETAILED DESCRIPTION 
     In one embodiment, a host auto classifier based on server classification is described. As described herein, a server may be a piece of computer hardware or software (computer program) that provides functionality for other programs or devices, called “clients.” This architecture is called the client-server model. Servers can provide various functionalities, often called “services,” such as sharing data or resources among multiple clients, or performing computation for a client. In one embodiment, servers may be classified according to “roles” (e.g., primary functionalities or responsibilities of the servers). Examples of server roles may include, but are not limited to, database servers, file servers, mail servers, print servers, web servers, game servers, and application servers. 
     Advantageously, almost every type of server can be optimized based on its role. For example, if a server is a network server, TCP optimization may be configured. If the server is a security/firewall server, the server may be optimized against DDOS attacks. Proper optimization requires that such servers are first of all categorized correctly. 
     Problematically, identifying a server role is difficult for a variety of reasons. Some organizations manage hundreds or thousands of servers and try to manage the classification of servers using methods like hostname or spreadsheets, but these methods are often prone to human errors as such methods primarily depend on proactive and precise human behavior. Furthermore, a server lifecycle might include a transition from one role to another, and such transitions are time consuming and difficult to track, especially over the entire duration of a server&#39;s lifecycle. Without proper tracking, server roles become even more difficult and time consuming to classify, as such requires one-by-one analysis and recordation by a human. 
     Without proper classification, server functionality may not be optimized, leading to subpar performance and wasted compute power and resources. When multiplied by the large number of servers maintained by many of today&#39;s companies, the problems described above are compounded and lead to massive inefficiencies. 
     In response to the problems described above, and others, automation of server classification is described herein. To make the optimization process automated today, a mechanism for classifying servers as network, security, storage, gaming, database, web, compute, etc. is described. In some embodiments, such optimizations may be run on entire datacenters without human intervention. 
     Advantageously, the embodiments of the present disclosure overcome the above, another other, challenges by providing for a host auto classifier based on server classifications. In one embodiment, such 
       FIG. 1A  is a block diagram that illustrates a first example system  100   a,  in accordance with some embodiments of the present disclosure.

In one embodiment, system  100   a  may be described as an apparatus  109 , including means for performing the operations described herein (e.g., server  101 , network  106 , client device  150 , etc.). In one embodiment, host role classifier  127  resides in whole or in part on a server (e.g., server  101 ) of system  100   a.

       FIG. 2  is a flow diagram of a first method  200  of the host auto role classifier, in accordance with some embodiments of the present disclosure. The method  200  may be performed by processing logic that comprises hardware (e.g., circuitry, dedicated logic, programmable logic, microcode, etc.), software (e.g., instructions run on a processing device to perform hardware simulation), or a combination thereof. In one embodiment, processing logic corresponding to one or more components of  FIG. 1A-C  may perform one or more of the following operations. For example, in one embodiment, processing logic of processing device  120  performs the following operations, with respect to the individual components of  FIG. 1A-C . In another embodiment, any other suitable processing device may perform the described operations. 
     Referring to  FIG. 2 , at block  202 , processing logic may receive one or more characteristics associated with a server of a datacenter. In another embodiment, the server does not necessarily reside in, or as part of, a datacenter. In one embodiment, such characteristics may include, for example:
         Network Traffic—This may include determining the type of traffic flowing in and out of the server.   Ports—E.g., which ports are open. For example, port 80 may mean that HTTP is used on the server.   Input/Output (I/O)—For example, if there is high I/O over a long period it might indicate the server is a file server.   Logs—Logs may provide an indication of information of actions that been made on the server and help classify it.   Processes—For example, by determining what is running, some part of the purpose of the server may be determined.   Kernel Parameters—E.g., processing logic may scan loaded modules and parameters&#39; values.   Packages—For example, by determining packages that are installed on the server, the classification analysis and determination may be focused in a specific area (for example, to determine if a server is indeed a file server processing logic may search for nfs, netapp, emc, packages).       

     At block  204 , processing logic may analyze (e.g., by a processing device) the one or more characteristics to determine a classification of the server. In one embodiment, the processing logic may make an accurate classification based off of a single characteristic of the server. In other embodiments, analysis of two or more characteristics may be required to make an accurate determination. In a variety of embodiments, characteristics may be analyzed according to the type of characteristic. For example, in one embodiment, the one or more characteristics may include network traffic characteristics, and analyzing the one or more characteristics may include determining a type of the network traffic. 
     In another embodiment, the one or more characteristics may include port characteristics, and analyzing the one or more characteristics may include determining an open port on the server. In another embodiment, the one or more characteristics may include input/output characteristics, and analyzing the one or more characteristics may include determining that there exists a high input/input to or from the server over a defined period of time. 
     In another embodiment, the one or more characteristics may include log characteristics, and analyzing the one or more characteristics may include determining one or more actions of server identified in the log characteristics. In another embodiment, the one or more characteristics may include process characteristics, and analyzing the one or more characteristics may include determining one or more processes run by the server. 
     In another embodiment, the one or more characteristics may include kernel parameter characteristics, and analyzing the one or more characteristics may include scanning one or more loaded modules or parameter values of the server. In another embodiment, the one or more characteristics may include package characteristics, and analyzing the one or more characteristics may include analyzing one or more packages installed on the server. As described above, in one embodiment the analyzing may be performed in view of at least two characteristics of the one or more characteristics. In another embodiment, a single characteristic may be used to perform the classification. Notably, the characteristics described herein are not exhaustive. For example, other characteristics that may be analyzed include those related to security firewall inputs, hardware profiles, directories and files—paths on the system, disk usage, CPU and memory, etc. 
     At block  206 , in view of the determined classification of the server, processing logic may modify one or more configurations (settings, features, functionalities, resource allocations, etc.) of the server to increase performance for one or more functionalities corresponding to the determined classification. In one embodiment, such modification may result in a single task being optimized. In another embodiment, more than one task of the server may be optimized in view of the classification. 
     By way of non-limiting example of the described method, in one embodiment the one or more characteristics may include network traffic characteristics and web port characteristics, and analyzing the one or more characteristics results in determining that the server is a web server. In such a case, configuration of the server may be modified to optimize functionality related to web servers (e.g., maximize throughput and bandwidth). In another example, processing logic may detect a major write to disk number of events (e.g., above a threshold), constant I/O events, a large number of mount points, file transfer ports are in use (e.g., 20, 21, 22), detection of storage-related packages, and/or found configuration files, each of which separately or together may indicate that the server is a storage server. In such a case, read and write functionality or other storage-related functionality may be optimized via a reconfiguration of the server. 
       FIG. 3  is a flow diagram of a second method  300  of the host auto role classifier, in accordance with some embodiments of the present disclosure. The method  300  may be performed by processing logic that comprises hardware (e.g., circuitry, dedicated logic, programmable logic, microcode, etc.), software (e.g., instructions run on a processing device to perform hardware simulation), or a combination thereof. In one embodiment, processing logic corresponding to one or more components of  FIG. 1A-C  may perform one or more of the following operations. For example, in one embodiment, processing logic of processing device  120  performs the following operations, with respect to the individual components of  FIG. 1A-C . In another embodiment, any other suitable processing device may perform the described operations. 
     Referring to  FIG. 3 , at block  302 , processing logic may analyze (e.g., by a processing device) two or more characteristics to determine two or more classification options of a server. In another embodiment, a single characteristic may be analyzed. Once analyzed, processing logic at block  304  may determine two or more confidence values for each of the at least two classification options, respectively (e.g., a first confidence value corresponding to the first option, and a second confidence value corresponding to the second option). In one embodiment, the two or more confidence values indicate a likelihood that the classification of the server is accurate. In one embodiment, the classification is based on multiple categories with a determined percentage-based confidence value indicating whether a classification is accurate and which metrics were used to classify it. 
     Confidence values may be computed using any number of suitable statistical models, and may be combined also using any number of models. In other embodiment, the values may simply be totaled (or weighted and totaled) to determine a final confidence score (value) based on the individual confidence values. For example, in one embodiment a result of a classification analysis may be similar to: Web server—70% confidence, Storage server—30% confidence. In such a case, it may be determined that the server is a web server. In some embodiment, a confidence level must be above a confidence threshold (e.g., 50%, 75%, 90%, etc.) to provide a determination of the classification. 
     As described herein, any number of characteristics may be used to determine a classification. The following non-exhaustive list is provided by way of example:
         Packages: List and inspect packages installed on the system. It is possible to classify each package to a specific area or product. For example, with a simple rpm-qi command, one can extract fields like Group, Description, and Summary which may determine if a certain package is related to the database, HTTP server, etc.   Ports: Certain ports serve specific purposes, like port  80  which is used for HTTP. By inspecting the ports on a certain server, processing logic may increase the classification probability.   Resource Consumption: Processing logic may check which processes or applications are most demanding from a resources perspective. It may be the case that for database (DB) or storage servers, for example, the most demanding process is the one installed on the host so that it can serve its purpose. In other words, it can be assumed that in a DB host the most demanding process will be the DB itself or a resource related to that process (e.g., a worker that can eventually be linked to the DB with process tree/inheritance).   Inspect the hardware: It may be beneficial to identify whether a certain host has special hardware specification by inspecting the hardware with different commands and paths such as lshw, lspci, dmidecode, . . . which can be parsed to identify whether GPU cards are installed or whether there is anything that is not ordinary for “normal” or common hosts. This can also increase the probability of whether a certain host is for example used for artificial intelligence or computational mathematics.   Network Traffic—Examination of packets may provide a lot of information. Packets have source and destination information, and processing logic knows where they are destined, based on layer 7 in the OSI model. As such, processing logic can classify traffic based on different patterns inspected with packet sniffers.   Logs—Logs may provide information related to actions that been made on the server and thus may help classify it. Processing logic is able to parse the logs with existing tools for getting the information needed, such as GET/SET commands, ports, and messages.   I/O—If there is high I/O over a long period it might indicate the server is a file server. Processing logic may receive I/O information and analyze which process is producing it, so there is a high probability that even non-high I/O but constant (or non-constant but for long periods) is generated by the main application running on the host. Also, no I/O at all (minimal) can indicate other information, such as the host being a network host perhaps (which can be confirmed by the intersection of I/O data with network patterns).   Processes—By viewing what is running, processing logic may determine some part of the purpose of the server. Also, determining which process is running helps to classify if this service is active or not. For example, processing logic determines that httpd rpm is installed, processing logic may estimate that it might be a web server, but if processing logic determines that the service is down it can indicate that it is not an active web server.   Kernel Parameters—Processing logic may scan loaded modules and parameters&#39; values. This by itself may not be enough to classify a host but can increase probability for classification based on other data. In one example, the result of one classification is that a certain host is a router host, which is used only for forwarding packets. If the kernel parameter that allows forwarding is disabled, then processing logic may disprove that assumption/initial classification.   Security/Firewall—Certain roles can indicate what is the purpose of the host. Determining rules enabled by the administrator (e.g., not default rules) may increase the probability of previous classification result.   Paths—Certain predefined paths can be checked and linked to processes in order to strengthen the previous classification. For example, if a path like /var/www is used then it might indicate the content is being served and this assumption can be verified by inspecting the processes and configuration of running processes.   Disk Usage—Processing logic can estimate from disk metrics whether the server is meant to hold a large amount of data. For example, on Linux servers, processing logic may use the “df-h” command and retrieve the disk sizes. On Windows servers processing logic can use diskmgmt.msc. If the server has one or more disks that hold multiple Terabytes of storage, for example, processing logic may analyze how it&#39;s used. By answering questions like “is the server writing there? Is it only reading from it? Which process is associated with using these terabytes of storage? Which package installed that process? Which user ran the process?, etc . . . ”, processing logic can increase the probability of the mechanism to classify the host.
