ID: 13486 Title: <tt>juniper_fru</tt>: Fix documentation for op. status "present" Component: Checks & agents Level: 1 Class: Bug fix Version: 2.1.0i1 The documentation of the check plugin <tt>juniper_fru</tt>, which monitors the power supplies of Juniper Ethernet Switch Chassis, incorrectly stated that an operational status of "present" results in the monitoring status OK. However, "present" results in WARN, which is correct and has been fixed in the documentation.
