Siemens PLC: CPU state

Distribution: official part of Check_MK
License: GPL
Supported Agents: SIEMENS_PLC

Monitors the current CPU state of Siemens PLC (SPS) devices.

You need to use and configure the special agent agent_siemens_plc which is using the SNAP7 library to communicate with the Siemens PLC. When you are using OMD, everything is already installed and configured. In manual setups, you will need to ensure that the snap7 library and python module snap7 are installed.

The CPU state can either be reported as running (OK), stopped (CRITICAL) and unknown (UNKNOWN).

One check for each device is created automatically.
