Custom Graphs
by alias＠kimber.net.au 11 Apr '13

Our weakness with xymon is forecasting disk trends. With the right thresholds I can be proactive in managing disk capacity however it's not possible to check the past 576days for hundreds of servers. Metric Reporting results are blank when selecting multiple hosts and disks however it does work for CPU but it compiles all results\servers into one graph . I would like to see disk trends of 200hosts display in 200graphs on the one page. Has anyone got any suggestions or "been there, done that" ? regards

Reverse DNS lookup check not working
by spah＠syntec.co.uk 11 Apr '13

11 Apr '13

There seems to be a bug where DNS PTR (Reverse DNS lookup) checks do not work in Xymon (4.3.7, but I don't recall seeing any fixes in the commits). The man page for hosts.cfg says the format to use is: dns=TYPE:lookup and one of the examples underneath for TYPE is PTR (reverse). I have tried this in small and capitals and neither work (the result is Name not found). Using A does work though. I wonder if it could be related to the fact that DiG needs to be invoked with -x for PTR checks. A quick look at the DiG man page suggests you could use either: # dig -t PTR my.ip.ad.dr.ess Or: # dig my.ip.ad.dr.ess PTR However, this is not the case. A closer looks reveals you have to use: # dig -x my.ip.ad.dr.ess So what I am saying is that the treatment for type PTR differs from the other types, and that the parameters supplied to DiG (if Xymon uses DiG ) differ for PTR. Tested manually with DiG 9.2.4 and the latest RHEL5: 9.3.6-P1-RedHat-9.3.6-20.P1.el5_8.6. Kind regards, SebA

Feature request: add description in hosts.cfg for conn multiple IP entry
by bewhite＠fellowes.com 11 Apr '13

Use the COMMENT keyword in your hosts.cfg entry and it will display on the web page.

Fellowes, Inc. -----Original Message----- From: xymon-bounces at xymon.com [mailto:xymon-bounces at xymon.com] On Behalf Of Deiss, Mark Sent: Wednesday, April 10, 2013 7:46 AM To: xymon Subject: [Xymon] Feature request: add description in hosts.cfg for conn multiple IP entry Maybe this is supported(?) or someone has a hack available: Would like to see support for a displayed description field for the hosts.cfg conn declaration for cases where there are multiple IPs. When there are a multiple IPs being tested on a given host, it can be a bit confusing figuring out what a particular failing IP is associated with. Ideally the description would show up in the status report to help identify the IP's purpose. For example in the hosts.cfg file: 1.2.3.1 main-host1 # conn=worst,1.2.4.10 (ILO address), 1.2.5.20 (PA-RISC Console port), 1.2.3.2 (Web Server Business Portal), 1.2.3.3 (Web Server https Business Portal), 1.2.3.4 (Oracle Listener/databases connections)...... In web status page: 1.2.3.1 is alive (1ms) 1.2.4.10 is alive (3 ms) ILO address 1.2.5.20 is alive (3 ms) PA-RISC Console port 1.2.3.2 is alive (1 ms) Web Server Business Portal 1.2.3.3 is unreachable Web Server https Business Portal 1.2.3.4 is alive (1 ms) Oracle Listener/databases connections The secondary IPs can be declared as separate entries in the hosts.cfg but that can lead to display "bloat". Even using the separate entries, there is still no user-friendly detail in the status messages on what is being tested. group-compress Operations 1.2.3.1 main-host1 # conn .... ... Group-compress ILO ports 1.2.4.10 main-host1 # conn .... Group-compress Console ports 1.2.5.20 main-host1 # conn .... Group-compress Web Servers ports 1.2.3.2 main-host1 # conn=worst,1.2.3.3 (so if the .3 address ip is unreachable, you don't know what the business impact is from just looking at the web status display) .... _______________________________________________ Xymon mailing list Xymon at xymon.com http://lists.xymon.com/mailman/listinfo/xymon

/etc/passwd Monitoring of Solaris Xymon Clients
by Nick＠Pettefar.com 10 Apr '13

Is there an established way of monitoring for /etc/passwd entriy changes/additions on Solaris servers? If not, is it possible to add it as a log to be fetched and then do some processing on the Xymon server? Regards, Nick Pettefar

vim config parser
by Phil.Crooker＠orix.com.au 10 Apr '13

10 Apr '13

Has anyone done a vim syntax file for xymon config files? I'm starting to look into it, but just wondering if anyone has done the work? A syntax file is the bit that colourises the syntactic elements of a language - eg bash or perl. If you are curious as well: http://vimdoc.sourceforge.net/htmldoc/syntax.html cheers, Phil

PROCS not monitored correctly -what is wrong with this picture?? (Find the error!) (LONG)
by betsy.schwartz＠gmail.com 09 Apr '13

09 Apr '13

My apologies to anyone who gets this on a digest I'm having some odd issues with procs on a database cluster and I would be very grateful for any clues! We have multiple rule sets to cut down on multiple alerts for shared disk, and because some have more capacity db0-db6 are Solaris 10 servers (there is no db8) running xymon 4.3.10 db11-db62 are RHEL Linux running a mix of xymon 4.3.10 and 4.3.7 server is a RHEL VM running xymon 4.3.10 Procs have been screwey for a while, but we only noticed when we added rngd testing to the linux boxes db1, db2, db3, db6 are alerting for missing rngd . db0, db4 and db5 are NOT (this is particularly puzzling since db5&db6 share a rule set, as do db0 and db1. I'd expect them to go as pairs. db1, db2, db3, and db6 all show: [image: green] cron (found 1, req. 1 or more)[image: green] nscd (found 1, req. 1 or more)[image: green] xntpd (found 1, req. 1 or more)[image: green] cron (found 1, req. 1 or more)[image: green] nscd (found 1, req. 1 or more)[image: green] ntpd (found 1, req. 1 or more)[image: yellow] rngd (found 0, req. 1 or more)[image: green] cron (found 1, req. 1 or more) db0, db4 and db5 all show: [image: green] cron (found 1, req. 1 or more)[image: green] nscd (found 1, req. 1 or more)[image: green] xntpd (found 1, req. 1 or more)[image: green] cron (found 1, req. 1 or more) That last cron comes from a HOST=* rule atthe end. Can you find what is wrong with the lines below? #-------------------#Database Servers HOST=%^db[0|1].example.com MEMPHYS 100 101 MEMSWAP 85 95 PROC cron 1 -1 yellow PROC nscd 1 -1 yellow PROC xntpd 1 -1 yellow # PROC sar -1 4 yellow LOAD 80.0 120.0 DISK /oracle/dba_msc_nfs2 101 101 DISK /oracle/data09 99 99 DISK /oracle/data10 97 98 DISK /oracle/data17 96 97 DISK /oracle/data22 98 99 DISK %.*archivelogs.* 90 95 DISK %.*redologs.* 90 95 DISK %.*data.* 95 96 LOG /export/home/xymon/client/tmp/powermt.out %degraded COLOR=yellow HOST=%^db[2|3|4|8].example.com UP 30m 9999d MEMPHYS 100 101 MEMSWAP 85 95 # LOAD 48.0 64.0 LOAD 80.0 120.0 PROC cron 1 -1 yellow PROC nscd 1 -1 yellow PROC xntpd 1 -1 yellow # PROC sar -1 4 yellow DISK %.*data.* IGNORE DISK %.*oracle.* IGNORE DISK %.*redologs.* IGNORE DISK %.* 80 90 LOG /export/home/xymon/client/tmp/powermt.out %degraded COLOR=yellow HOST=%^db[5|6].example.com UP 30m 9999d MEMPHYS 100 101 MEMSWAP 85 95 LOAD 160.0 240.0 DISK /oracle/export02 90 95 DISK %.*oracle.* IGNORE DISK %.* 80 90 PROC cron 1 -1 yellow PROC nscd 1 -1 yellow PROC xntpd 1 -1 yellow # PROC sar -1 4 yellow LOG /export/home/xymon/client/tmp/powermt.out %degraded COLOR=yellow HOST=%^db[11|12|13|21|22|23|31|32|33|61|62].bo3.* UP 30m 9999d MEMPHYS 100 101 MEMSWAP 85 95 LOAD 64.0 128.0 PROC cron 1 -1 yellow PROC nscd 1 -1 yellow PROC ntpd 1 -1 yellow PROC rngd 1 -1 yellow (there are usually more LOG lines but I removed them for clarity, and verified that the errors persist)

Xymon -- Page Refresh
by g.fer.ordas＠unicyber.co.uk 08 Apr '13

08 Apr '13

Hi I am having a look at the possibility of changing the REFRESH for the webpages, or to disable it!!! as 60 seconds for some webpages it is too little when you got a big bunch of graphs, but changing and hard-coding the template will impact on all the other pages as well. I also could not find the actual variable and I did not know where to change it but hard-coding.. (Unless this has been compiled in the cgi files..) Any thoughts around this at all? Many thanks for all your help. Gonzalo.
