|
|
+## Overview
|
|
|
+
|
|
|
+This collector monitors the activity and performance of MaxScale servers.
|
|
|
+
|
|
|
+
|
|
|
+It sends HTTP requests to the MaxScale [REST API](https://mariadb.com/kb/en/maxscale-24-02rest-api/).
|
|
|
+
|
|
|
+
|
|
|
+This collector is supported on all platforms.
|
|
|
+
|
|
|
+This collector supports collecting metrics from multiple instances of this integration, including remote instances.
|
|
|
+
|
|
|
+
|
|
|
+### Default Behavior
|
|
|
+
|
|
|
+#### Auto-Detection
|
|
|
+
|
|
|
+The collector can automatically detect MaxScale instances running on:
|
|
|
+
|
|
|
+- localhost that are listening on port 8989
|
|
|
+- within Docker containers
|
|
|
+
|
|
|
+> **Note that the MaxScale REST API requires a username and password**.
|
|
|
+> While Netdata can automatically detect MaxScale instances and create data collection jobs, these jobs will fail unless you provide the necessary credentials.
|
|
|
+
|
|
|
+
|
|
|
+#### Limits
|
|
|
+
|
|
|
+The default configuration for this integration does not impose any limits on data collection.
|
|
|
+
|
|
|
+#### Performance Impact
|
|
|
+
|
|
|
+The default configuration for this integration is not expected to impose a significant performance impact on the system.
|
|
|
+

|
|

|
|
+## Metrics
|
|
|
+
|
|
|
+Metrics grouped by *scope*.
|
|
|
+
|
|
|
+The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.
|
|
|
+
|
|
|
+
|
|
|
+
|
|
|
+### Per MaxScale instance
|
|
|
+
|
|
|
+These metrics refer to the monitored MaxScale instance.
|
|
|
+
|
|
|
+This scope has no labels.

|
+## Troubleshooting
|
|
|
+
|
|
|
+### Debug Mode
|
|
|
+
|
|
|
+**Important**: Debug mode is not supported for data collection jobs created via the UI using the Dyncfg feature.
|
|
|
+
|
|
|
+To troubleshoot issues with the `maxscale` 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 maxscale
|
|
|
+ ```
|
|
|
+
|
|
|
+### Getting Logs
|
|
|
+
|
|
|
+If you're encountering problems with the `maxscale` collector, follow these steps to retrieve logs and identify potential issues:
|
|
|
+
|
|
|
+- **Run the command** specific to your system (systemd, non-systemd, or Docker container).
|
|
|
+- **Examine the output** for any warnings or error messages that might indicate issues. These messages should provide clues about the root cause of the problem.
|
|
|
+
|
|
|
+#### System with systemd
|
|
|
+
|
|
|
+Use the following command to view logs generated since the last Netdata service restart:
|
|
|
+
|
|
|
+```bash
|
|
|
+journalctl _SYSTEMD_INVOCATION_ID="$(systemctl show --value --property=InvocationID netdata)" --namespace=netdata --grep maxscale
|
|
|
+```
|
|
|
+
|
|
|
+#### System without systemd
|
|
|
+
|
|
|
+Locate the collector log file, typically at `/var/log/netdata/collector.log`, and use `grep` to filter for collector's name:
|
|
|
+
|
|
|
+```bash
|
|
|
+grep maxscale /var/log/netdata/collector.log
|
|
|
+```
|
|
|
+
|
|
|
+**Note**: This method shows logs from all restarts. Focus on the **latest entries** for troubleshooting current issues.
|
|
|
+
|
|
|
+#### Docker Container
|
|
|
+
|
|
|
+If your Netdata runs in a Docker container named "netdata" (replace if different), use this command:
|
|
|
+
|
|
|
+```bash
|
|
|
+docker logs netdata 2>&1 | grep maxscale
|
|
|
+```
|
|
|
+
|
|
|
+
