nextcloud monitoring using checkmk

 if you have trouble to get the checkmk exchange nextcloud plugin running, this content may be helpful for you.



plugin / mkp package:

https://exchange.checkmk.com/p/nextcloud



[ version: [special_nextcloud_data] Version: 25.0.2.3 ]

[ checkmk version: 2.0.0p12 ]



>> we had no success in getting the data out from nextcloud by configuring the plugin using the checkmk webfrontend, so we made some deep dive on the console:



OMD[yoursite]:~local/share/

OMD[yoursite]:~/local/share$ ./check_mk/agents/special/agent_nextcloud_data -u yourUsername -p yourPassword nextcloud.yourdomain.com



now we got the following error message:

-------------------------------------------------------------------

>>> by debugging the script, we found out that the problem was a special character in the password, we used a § and a $ sign. 

Without this characters - with only a ! as special character the plugin is working
