# New Functionality for Moodle E-Learning Platform: Files Communication by Chat Window
## 3 Purpose of Sending Files through the Chat Window
### Analyzing the Impact of the Developed Method
As a result of thirty-day monitoring at the Windows system information/ManageEngine level, 43 warnings were received, 16 incidents were identified, and no problem was reported. After three days of monitoring at the CPU usage level, 7% CPU usage and a speed of 3.86 GHz per 60 s were observed. Following weekly CPU usage monitoring, CPU usage of 12% and a speed of 3.22 GHz per 60 s were identified. As a result of thirty-day CPU usage monitoring, CPU usage of 19% and a speed of 3.47 GHz per 60 s were identified. Following the monitoring performed three times a day at the server memory level, a memory usage of 24.5 GB was identified, with the free memory being 104 GB. Following the monitoring performed for one week at the server memory level, memory usage of 26.3 GB was identified, with the free memory being 101 GB. After thirty days of server memory monitoring, a memory usage of 25.6 GB was discovered, with 102 GB of available memory. Following the monitoring performed three times a day at the HDD hard disk server level for one day, a response time of 0.6 ms, a write speed of 64.9 KB/s, and a free space of 86% were identified. Following weekly monitoring of the HDD hard disk server, a response time of 0.5 ms, a write speed of 72.8 KB/s, and 77% free space were identified. Following 30-day monitoring of the HDD hard disk server, a response time of 0.7 ms, a write speed of 70.4 KB/s, and 81% free space were identified. According to reports provided by network monitoring, there was an increase in data traffic on the days of and before exams and tests. Even if the hits increased, the server was not overloaded and was working within normal parameters. Alsoin the same days, there were increases in processor and memory, but performance was not affected, operating within normal parameters. The processor and memory did not undergo increases that would lead to the degradation of operating parameters. No problems were reported, and the number of incidents and warnings were within normal parameters, not registering a significant increase compared to the period and number of users. No viruses were identified, but the number of spam messages increased, according to reports provided by the antivirus program. Throughout this period, users' workstations were monitored 24 h a day for 30 days. Throughout the development and use of the implemented solution, a series of actions were carried out at the user level aimed at obtaining feedback on the new solution. These actions consisted of the following:  
Questionnaires sent by email;  
Receiving submitted questionnaires;  
Sample phone calling of users;  
Interpreting/analyzing the answers received. In addition, the logs from the components related to the implemented solution were analyzed as follows:  
System logs on the station;  
Antivirus logs (BitDefender);  
Logs from network station scanning programs (ManageEngine);  
Logs from scanning data traffic (Wireshark);  
Application specific logs, as well as from other related programs. Following the positive results from users and the analysis of the systems in the logs mentioned above, the decision was made to go into production. Currently, over 550 people use the presented solution, and the target is to be used by all employees, namely a total of 2500. Every month, 300 accounts are activated. The challenges we started with in this implementation of the solution were the non-existence of this way of transmitting files within the Moodle platform and the need to introduce this new method, which has an impact on the communication process that is beneficial to users. During the implementation process, we tried to go beyond how communication through the chat window exists and works on the Moodle platform.
