Proxy Error

[guif]

Hi,

After install via this on a Raspberry PI Zero:

curl -LO $(curl -s https://api.github.com/repos/chrisss404/check-mk-arm/releases/tags/2.0.0p8 | grep browser_download_url | cut -d '"' -f 4 | grep buster_armhf.deb) 
dpkg -i check-mk-raw-2.0.0p8_0.buster_armhf.deb

And check all services OK:

root@checkmk:~# su - monitor
OMD[monitor]:~$ omd status
mkeventd:       running
rrdcached:      running
npcd:           running
nagios:         running
apache:         running
redis:          running
crontab:        running
-----------------------
Overall state:  running

Appears on browser this:

Proxy Error
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request

Reason: Error reading from remote server

Apache/2.4.38 (Raspbian) Server at 10.0.1.16 Port 80

What's wrong?

Hi guif,

judging from the error logs you provided in the checkmk forum you are experiencing a timeout that is caused by the fact that checkmk is taking too long to respond.

You can try to increase the timeout in /omd/sites/monitor/etc/apache/proxy-port.conf, but most likely your RPi is not able to handle this version of checkmk due to insufficient hardware resources. Issue #29 might be related.

Thanks Christian. I'm waiting for the new version.
