Turning Hostname into Hyperlink Changes Graph Titles
by oakesbz＠gmail.com 16 Jul '15

16 Jul '15

Hi all, I’m using the below to turn my hostnames into hyperlinks to login to each server (which works great): 10.10.10.10 Hostname # NAME:"<a href=ssh://root at 10.10.10.10>Displayed Hostname</a>" Problem is, it now uses this ugly html string as the hostname in the title of my graphs. So it displays "<a href=ssh://root… > Disk Utilization”, etc. as the title… which is obviously not pretty. Any thoughts on how to fix this? By the way, it also changes the displayed hostname in several other places which I managed to fix by changing the variable &XYMWEBHOST to &XMH_HOSTNAME in several of the $xymon/server/web/*_header files… Thank you!

Attempt to change default port
by dewelker＠gmail.com 15 Jul '15

15 Jul '15

I've successfully installed Xymon 4.3.21, but tried to change it from the default port of 1984 by changing the XYMONDPORT variable in xymonserver.cfg. Unfortunately, this turned the cpu, disk, files, etc. all purple. The bbd, conn, http, and xymon status' are all green.. Is there something else I need to change to be able to run Xymon from another port? Thanks, David

Alerts stop working

Hi Guys, Recently I have started to have a problem where alerts stop sending emails and I'm not sure how exactly to troubleshoot. This has happened a few times over the last few weeks, my solution at the moment is to restart the xymon service in Debian and this fixes the problem and I start seeing emails again. This is what I have done so far: - Check the notifications log when I notice the emails have stopped, log has not been updated although I would expect to see something here as I can see tests going yellow/red in xymon. - Pick a host that currently has a yellow/red alert and run xymoncmd xymond_alert --test hostname msgs it matches the rule and matches script to send an email - If I run a command like RCPT=bdale at kitchengroup.com.au BBHOSTSVC=my.host.dom.cpu BBCOLORLEVEL=red BBHOSTNAME=my.host.dom BBSVCNAME=cpu xymoncmd ./html_mail.pl it sends an email successfully. If I restart the xymon service then I start to see the notifications.log file start updating again.. how can I troubleshoot? This seems to happened every few days, I'm running 4.3.21. Regards, Brandon

Xymon server report purple because custom client script do not report often enough
by hobbit＠weiser.dk 11 Jul '15

11 Jul '15

Hey, I have made a script which count how many times a string appears in a log file. Nothing special. And it works fine. Doing the testing of this script I made the interval to 1m, just so I did not have to wait to long to test changes. Now that I finish with the script I want the interval, configured in clientlaunch.cfg, to run every 60m, so I have changed it in clientlaunch.cfg. But that result in the xymon server is complaining about stop reporting from the client on this custom check. I have tried to delete the test status from the server, but with no luck. Is there something I have misunderstood and is there a way to fix it? Clientlaunch.cfg [razor-count] ENVFILE $HOBBITCLIENTHOME/etc/hobbitclient.cfg CMD $HOBBITCLIENTHOME/ext/razor-report-count.sh LOGFILE /var/log/hobbit/razor-report-count.log INTERVAL 60m Thanks, Kim.

All Xymon rrd graphs suddenly haywire
by rectifier＠gmail.com 10 Jul '15

Hi all, This weekend, something happened with all our graphs. Every hosts' graphs are either corrupted or distorted and the history is unusable. I have checked all the usual places for graphs logging, rrd-data.log and rrd-status.log and other system log files but I am stumped as to where to start fixing this. We are looking at restoring rrds from previous snapshot which may or may not work but still would like to solve this mystery. I have attached 2 screens but I do not know if these are viewable on the mailing list. It is hard to explain without but essentially there are huge numbers in our graphs such 3945789385793485793847593847593847593847593847593845793485739 and lots of '?' and there is no usable history, just a straight line along the base with one peak (or two) around the time this all happened (with a day or two out either way). If you try to zoom in, you get to a screen that just says 'zoom source image' and it's a black screen but if you hover your mouse over the screen you can find an area that is selectable and this shows a close up of the zoom area rrdtool info example (for the same screenshot host test): filename = "disk,C.rrd" rrd_version = "0003" step = 300 last_update = 1436270189 ds[pct].type = "GAUGE" ds[pct].minimal_heartbeat = 600 ds[pct].min = 0.0000000000e+00 ds[pct].max = 1.0000000000e+02 ds[pct].last_ds = "89" ds[pct].value = 7.9210000000e+03 ds[pct].unknown_sec = 0 ds[used].type = "GAUGE" ds[used].minimal_heartbeat = 600 ds[used].min = 0.0000000000e+00 ds[used].max = NaN ds[used].last_ds = "28436524" ds[used].value = 2.5308506360e+09 ds[used].unknown_sec = 0 rra[0].cf = "AVERAGE" rra[0].rows = 576 rra[0].pdp_per_row = 1 rra[0].xff = 5.0000000000e-01 rra[0].cdp_prep[0].value = NaN rra[0].cdp_prep[0].unknown_datapoints = 0 rra[0].cdp_prep[1].value = NaN rra[0].cdp_prep[1].unknown_datapoints = 0 rra[1].cf = "AVERAGE" rra[1].rows = 576 rra[1].pdp_per_row = 6 rra[1].xff = 5.0000000000e-01 rra[1].cdp_prep[0].value = 4.4500000000e+02 rra[1].cdp_prep[0].unknown_datapoints = 0 rra[1].cdp_prep[1].value = 1.4218146600e+08 rra[1].cdp_prep[1].unknown_datapoints = 0 rra[2].cf = "AVERAGE" rra[2].rows = 576 rra[2].pdp_per_row = 24 rra[2].xff = 5.0000000000e-01 rra[2].cdp_prep[0].value = 2.0470000000e+03 rra[2].cdp_prep[0].unknown_datapoints = 0 rra[2].cdp_prep[1].value = 6.5402986560e+08 rra[2].cdp_prep[1].unknown_datapoints = 0 rra[3].cf = "AVERAGE" rra[3].rows = 576 rra[3].pdp_per_row = 288 rra[3].xff = 5.0000000000e-01 rra[3].cdp_prep[0].value = 1.2727000000e+04 rra[3].cdp_prep[0].unknown_datapoints = 0 rra[3].cdp_prep[1].value = 4.0657944878e+09 rra[3].cdp_prep[1].unknown_datapoints = 0 This weekend we had a network intervention in that we moved some network connections in one of the 2 data centers but there was no downtime as we switched the network connectivity to the other data room. Our Xymon server is running on a virtual server (RHEL5) and the version we are using is 4.3.19. All graphs were fine until this point. Any ideas?

Renaming Host
by neilsimmonds1808＠gmail.com 09 Jul '15

09 Jul '15

Hi all, I've had to rename a host in Xymon today and realised the shortcomings of Xymon for this. Has anyone got a script (linux Xymon server) that will move the histlogs data and hostdata to the new name rather than just the hist data like the built in rename command does? I'm not sure if I can just move the files to the new folders or if the data in the files needs tweaking as well. Any suggestions would be very welcome. Regards, Neil Simmonds

Rookie having trouble with disk test
by haley787＠erau.edu 08 Jul '15

08 Jul '15

I am running xymon 4.3.17 on both the server and client. The disk service status graph is not showing a mount I added a couple days ago, but the trends graph is. I'm pretty green with xymon and can't work out why there's a mismatch between the graphs. Any help would be appreciated. Thanks!

Select All on Acknowledge page?
by skadz＠skadz.com 08 Jul '15

08 Jul '15

Has anyone hacked together a select all for the acknowledge page? We've had a few major attacks recently and trying to ack 200 alerts takes more time than trying to actually fix the problem. It would be great if I could just hit select all and then the ack button. Thanks! Skadz
