[Xymon] http checks red with timeout, xymonnet fast

[Schrittenlocher, Rolf]

Hi Jeremy and others,

thanx for help

Can you show the red alert page for a failed https test?

Wed Apr 28 09:02:48 2021: Server timeout[red] https://xxx - Server timeout


Seconds:    18.92

Is there anything showing in the xymonnet.log file?
no, empty

What is the status of the xymonnet test page for your Xymon server? (This will probably show the most recent messages from the xymonnet.log file, among other info.)

not quite sure what that test page is. I added a http check http://our_xymon_server/xymon-cgi/svcstatus.sh?HOST=our_xymon_server&SERVICE=http  for our xymon server (no certifcate, no https) and the result  is interesting. It alternates between less than 1 second and timeout

When running xymonnet, are you switching to xymon user and running xymoncmd to setup the environment?

I did it as xymon user but without xymoncmd. Did it again with xymoncmd, very little difference.

Once again. Error occured at a time where noone was doing any changes. Switching xymon server to another machine in the same subnet everything is fine. xymon, apache, etc. installation on both machines is identical only hardware differs.

Any ideas?

Greetings

Rolf

Cheers
Jeremy

Dear all,


>From one moment to the next we had the situation that all our https tests went to red because of timeouts. As far as we found no firewall or network issue. Using another machine everything is fine. We assume a hardware problem with the main board (Sun T3 Solaris), but support says the machine is ok. Doing the request directly with xymonnet the result is a quick reply. Any ideas how to debug this or what I am doing wrong? Where is a difference between the check made by xymon server and the manual check? We are using xymon 4.3.17


example entry in hosts.cfg:

ip   column_name            # noconn HIDEHTTP cont=xxx;https://address?id=354400185;keyword

Result: Server timeout Seconds: 18.94


console:

xymonnet --timing  --ssl=ssl --content=keyword https://address?id=354400185

Result: TIME TOTAL          0.011761


Any help appreciated,

regards

Rolf
