3. Configure connection information using macros

• Go to the host configuration page,

• open the Macros tab,

• configure required parameters.

The following parameters are available:

• {$COUCHDB_HOST}: the CouchDB host (optional, default: localhost)

• {$COUCHDB_PASSWORD}: the password to connect to CouchDB (required)

• {$COUCHDB_PORT}: the CouchDB port (optional, default: 5984)

• {$COUCHDB_PROTO}: the protocol to use to connect to CouchDB (http or https, optional, default: http)

• {$COUCHDB_USER}: the user to connect to CouchDB (optional, default: admin)

At least the {$COUCHDB_PASSWORD} macro must be defined!

About polling interval

The default polling interval of this probe in Zabbix is 30s. In order to have accurate stats, you must configure the “stats interval” setting of your CouchDB to twice this value (60s):

[stats]
interval = 60
