Problem
You receive error messages like the following.
| Code Block |

|
Fetcher for host "$HOST" times out after X seconds |
Background
Read this section about helper processes in Checkmk to understand the following.
There are several reasons why a fetcher might time out. Below is a listing of some typical reasons.
Plugins and local checks
Sometimes a plugin or a local check needs a very long time to provide data or will not provide data at all.
Depending on your Microcore timeout - which defaults to 60 seconds - you reach the timeout and receive the error message from above.
Use the following commands to time the agent execution time:

time /usr/bin/check_mk_agent |

Solution

Plugins and local checks
Plugin or local check never finishes
If the plugin or local check throws errors or never finishes, you must learn how to fix this.
Plugin or local check finishes after a long time
In case the plugin or local check finished but needs longer than the Microcore timeout, you can run the plugin asynchronously. Use the Set cache age for plug-ins (UNIX) rule for UNIX-like OS and the "Set execution mode for plug-ins and local checks" rule for Windows.
