Title: PostgreSQL: Differentiate idle from active connections
Component: Checks & agents
Level: 1
Class: New feature
Version: 1.7.0i1
Previously, the agent plugin "mk_postgres" and the check plugin
"postgres_connections" were not differentiating between "idle" and
"active" connections.
With this werk, the data to differentiate those states is obtained and evaluated
accordingly.
The WATO rule "Database Connections (PostgreSQL)" (renamed from "Database
Connections (PostgreSQL/MongoDB)") has now a dedicated option for setting the levels
for "active" and "idle" connections.
In case the rule was used previously, the default connection type for PostgreSQL will be
"active" as the old agent was excluding "idle" connections.
<b>Note:</b> As this WATO rule was applicable as well for MongoDB, this change
will be incompatible to previously existing MongoDB rules set with "Database
Connections (PostgreSQL/MongoDB)". If this is applicable for your setup, perform the
following steps:
<li> If you're monitoring both PostgreSQL <b>and</b> MongoDB: keep
the old rule "Database Connections (PostgreSQL/MongoDB)" before updating to this
werk.</li>
<li> If you're monitoring MongoDB <b>only</b>: delete the old rule
"Database Connections (PostgreSQL/MongoDB)" before updating to this
werk</li>
<li> Create a new rule with your previous settings for MongoDB with the new rule
"Database Connections (MongoDB)" </li>
