ProxySQL monitoring with Netdata

ProxySQL is an open-source proxy for mySQL.

This module monitors one or more ProxySQL servers, depending on your configuration.

Metrics

All metrics have "postgres." prefix.

Labels per scope:

global: no labels.
command: command.
user: user.
backend: host, port.

Configuration

Note: this collector uses stats username and password which is enabled by default.

Edit the go.d/proxysql.conf configuration file using edit-config from the Netdata config directory, which is typically at /etc/netdata.

cd /etc/netdata # Replace this path with your Netdata config directory
sudo ./edit-config go.d/proxysql.conf

DSN syntax in details.

jobs:
  - name: local
    dsn: '[username[:password]@][protocol[(address)]]/'
    # username:password@protocol(address)/
    # Examples:
    # - name: remote
    #   dsn: stats:stats@localhost/

For all available options see module configuration file.

Troubleshooting

To troubleshoot issues with the proxysql 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].
```
cd /usr/libexec/netdata/plugins.d/
```
Switch to the netdata user.
```
sudo -u netdata -s
```
Run the go.d.plugin to debug the collector:
```
./go.d.plugin -d -m proxysql
```
