This collector is supported on all platforms. This collector supports collecting metrics from multiple instances of this integration, including remote instances. This collector discovers Chrony instance running on the local host and listening on port 323. On startup, it tries to collect metrics from: 127.0.0.1:323 The default configuration for this integration does not impose any limits on data collection. The default configuration for this integration is not expected to impose a significant performance impact on the system. Metrics grouped by scope. The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels. These metrics refer to the entire monitored application. This scope has no labels. Metrics: | Metric | Dimensions | Unit | |:|:-|:-| | chrony.stratum | stratum | level | | chrony.currentcorrection | currentcorrection | seconds | | chrony.rootdelay | rootdelay | seconds | | chrony.rootdispersion | rootdelay | seconds | | chrony.last_offset | offset | seconds | | chrony.rms_offset | offset | seconds | | chrony.frequency | frequency | ppm | | chrony.residualfrequency | residualfrequency | ppm | | chrony.skew | skew | ppm | | chrony.updateinterval | updateinterval | seconds | | chrony.refmeasurementtime | refmeasurementtime | seconds | | chrony.leapstatus | normal, insertsecond, delete_second, unsynchronised | status | | chrony.activity | online, offline, burstonline, burstoffline, unresolved | sources | There are no alerts configured by default for this integration. No action required. The configuration file name for this integration is `go.d/chrony.conf`. You can edit the configuration file using the `edit-config` script from the Netdata . ```bash cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata sudo ./edit-config go.d/chrony.conf ``` The following options can be defined globally: updateevery, autodetectionretry. <details><summary>Config options</summary> | Name | Description | Default | Required | |:-|:--|:-|:--:| | update_every | Data collection frequency. | 5 | no | | autodetection_retry | Recheck interval in seconds. Zero means no recheck will be scheduled. | 0 | no | | address | Server address. The format is IP:PORT. | 127.0.0.1:323 | yes | | timeout | Connection timeout. Zero means no timeout. | 1 | no | </details> A basic example configuration. ```yaml jobs: name: local address: 127.0.0.1:323 ``` Note: When you define multiple jobs, their names must be unique. Collecting metrics from local and remote instances. <details><summary>Config</summary> ```yaml jobs: name: local address: 127.0.0.1:323 name: remote address: 192.0.2.1:323 ``` </details> To troubleshoot issues with the `chrony` collector, run the `go.d.plugin` with the debug option enabled. The output should give you clues as to why the collector isn't working. Navigate to the `plugins.d` directory, usually at `/usr/libexec/netdata/plugins.d/`. If that's not the case on your system, open `netdata.conf` and look for the `plugins` setting under `[directories]`. ```bash cd /usr/libexec/netdata/plugins.d/ ``` Switch to the `netdata` user. ```bash sudo -u netdata -s ``` Run the `go.d.plugin` to debug the collector: ```bash ./go.d.plugin -d -m chrony ```
