Monitoring replication slave

How to monitor the slave status using the plugin.

Solution

Since arangodb ,integrating it with the collectd curl_JSON pluginshould be an easy exercise. However, only very recent versions of collectd will handle boolean flags correctly.

Since replication appliers are active per database and our example doesn’t use the default , we need to specify its name in the URL like this: _db/testDatabase.

We need to parse a document from a request like this:

A running replication will return something like this:

We create a simple collectd configuration in /etc/collectd/collectd.conf.d/slave_testDatabase.conf that matches our API:

So, basically state/running will give you 0/1 if its (not / ) running through the collectd monitor.
