After a low activity period (or rather, after highest activity period), we release this week a Nagios plugin very useful for those who use Cisco devices. check_cisco_envmon uses data stored in CISCO-ENVMON MIB for checking the hardware components status and the discrete levels of their functional values.

Plugin allows you checking the operational status of power supplies, fans, voltage and temperature levels managing these values:

• Normal: The component or checked value is healthy or in the operational value range.
• Warning: Component with degraded working state or values out of range but still not reaching critical values.
• Critical: Component working state is critical or the checked value level has raised critical values.
• Shutdown: Component status or value level is so degraded that the device will shutdown for auto protection.
• Not Present: Checked component is not present.
• Not Functioning: Checked component reports abnormal values, thus not functioning state is considered.

Relative to functional values, plugin returns voltage levels and temperature values as performance data.

We would like to thank Marcia Gross her help lighting our way in order to select what plugin to release this week (Marcia, we hope it has most useful for you).
