Checkmk Werk 11363: if64, if64adm: Monitoring of the admin status <tt>ifAdminStatus</tt> for switch ports

ID: 11363 Title: if64, if64adm: Monitoring of the admin status <tt>ifAdminStatus</tt> for switch ports Component: Checks & agents Level: 1 Class: New feature Version: 1.7.0i1 The 64-bit version of the interface check for switch ports can be configured to also monitor the admin status <tt>ifAdminStatus</tt>. If this option is activated, checkmk uses the check plugin <tt>if64adm</tt> instead of <tt>if64</tt>. Up to now, only an <tt>ifAdminStatus</tt> of 2 was reported by setting the port state to <i>9 - admin down</i>. With this werk, the admin status is now monitored completely separately from the port state. Consequently, the port state <i>9 - admin down</i> is not available any more. Previously, the monitoring of the admin state was activated implicitly by configuring checkmk to discover ports in the state <i>9 - admin down</i> (rule "Network Interface and Switch Port Discovery"). Now, this is handled in a separate rule: "SNMP Interface check: Monitor ifAdminStatus (use 'if64adm' instead of 'if64')". If and only if this rule is activated, the admin status will be monitored, independently of the configuration in "Network Interface and Switch Port Discovery". Furthermore, since the admin status is now reported separately from the port state, it can also be used to configure 1) the discovery of network interfaces (rule "Network Interface and Switch Port Discovery"), 2) the monitoring state (rule "Network interfaces and switch ports"). For example, you can make checkmk discover only interfaces with an admin status of 2 or you can set the monitoring state of all interfaces with an amdin status of 1 to WARNING. Note that these configuration options only have an effect if the admin status is actually monitored, i.e., if the new rule mentioned above is activated. This change is incompatible for all users who are currently monitoring the admin status using <tt>if64adm</tt>. These users should follow these steps: <ul> <li>Activate the monitoring of the admin status using the new rule "SNMP Interface check: Monitor ifAdminStatus (use 'if64adm' instead of 'if64')". </li> <li>Check the discovery configuration (rule "Network Interface and Switch Port Discovery"). As mentioned above, the admin state can now be used to further refine the discovery of network interfaces. On the other hand, the port state <i>9 - admin down</i> is not available any more, so users might have to adjust their configurations.</li> <li>Re-discover the services of affected hosts.</li> <li>Check the monitoring configuration (rule "Network interfaces and switch ports"). Analogously to the discovery configuration, the admin state can now be used to set the monitoring state of network interfaces and the port state <i>9 - admin down</i> is not available any more.</li> </ul>
