.default. not working?
by jdustin＠usm.maine.edu 16 Apr '12

16 Apr '12

Greetings - I'm currently running Xymon v4.3.7, and having troubles getting the ".default." entry to work properly. Here is what I have configured: page devs Network Devices 0.0.0.0 .default. # testip NOPROPRED:if_load NOPROPYELLOW:if_load (then a bunch of hosts below) It seems the .default. entry is ignored (status IS propagated upward), *and* I see the following error in xymonnet: dnsresolve - internal error, name '' not in cache xymonnet: Cannot resolve IP for host Am I misunderstanding the ".default." entry? Thanks for anything you can pass along. -- Jon Dustin - Network Specialist University of Southern Maine Portland, ME 207-780-4152

Example of rrd.meta use ?
by joel＠carnat.net 14 Apr '12

14 Apr '12

Hello, I'm writing a script to show disk temperature. I read about "RRDMETA" that "(...)if you create a file called rrd.meta in the hosts rrd directory, it will lookup a legend in this file(...)". But I didn't found the information about the format and how it is used by xymon. What is the preferred way to fill-in such rrd.meta file ? Is there any xymon command (like status or data) to use or does it have to be edited statically ? TIA, Jo

TIME_WAIT making client report too big
by hobbit＠elyograg.org 14 Apr '12

14 Apr '12

I have a couple of servers that I just started monitoring. These servers exist to run haproxy, a load balancer. The haproxy program tends to leave a lot of TIME_WAIT connections in the netstat output. This is resulting in a client report that is too big, and I am getting false red alarms on procs, because it can't find the cron process. Is there any way to have specific clients filter out TIME_WAIT before sending in their reports? If so, can it be controlled from the server? I have also been looking for ways to make haproxy clean up after itself better, but that so far is a dead end. The client is CentOS 6 running 4.3.7 from a package, the server is running 4.3.0 beta using packages in the debian repository. I know I need to get it upgraded. It's on my todo list, but because of the hobbit->xymon change throughout the program, upgrading is not going to be pretty, and I keep putting it off. Thanks, Shawn

Additional tests from xymon server
by damian.ioan＠gmail.com 13 Apr '12

13 Apr '12

Hi, I'm trying to add a test to the xymon server. This one has to reside server-side because not it does domain checks and not all domains have an assigned IP. Also, connectivity is not a concern here. What I'm trying to do is add some domain in a subpage and check for changes in their nameserver IPs. I've written a perl script that does the job and it takes the domain name as a parameter. In practice I'm trying to replicate what xymonnet does with the various checks like dns, http, smtp, etc. I would have something like this hosts.cfg: page domainchecks <H3>Domain Checks<H3> <some IP> <the domain name> # noconn <my_test_name> I did scrip this to check all domains at once but, that's not a desired behavior because I need to xymon to treat them separately and tell me for each if something changed or not according to my script. I setup a test task in tasks.cfg like this: [Environment] ENVFILE /var/lib/xymon/server/etc/xymonserver.cfg NEEDS xymond CMD $XYMONSERVERROOT/server/ext/env.pl LOGFILE $XYMONSERVERLOGS/ext-env.log INTERVAL 5m I've set it up for some hosts to no avail: <some ip> <hostname> # env It only shows up for the xymon server, which leads me to think this is more cumbersome than I first thought. Has anyone managed to do something like this before? -- All I know is that I like you. I have no taste, but I like you.

Xymon Service alert not showing proper status for stopped service - windows
by Don.Kuhlman＠schawk.com 13 Apr '12

13 Apr '12

Hi folks. I just received this alert and am trying to figure out why it's showing this way. It's alerting on a service on a windows sql box - the service that looks stopped is SQLSERVERAGENT automatic stopped SQL Server Agent (MSSQLSERVER) but the alert text shows &red SQLSERVERAGENT is started/automatic - want started/automatic Is this a time delay, or is there something I'm missing that's causing the disconnect ? Will Xymon try to restart this service or do we manually code something to do that? My goal is to setup specific MYSQL and MS SQL server monitoring on a DB page, but I hope to get a better understanding of how to watch and validate these items. Thanks Don K red Fri Apr 06 13:02:17 2012 - Services NOT ok &green MSSQLSERVER is started/automatic - want started/automatic &green SQLBrowser is started/automatic - want started/automatic &red SQLSERVERAGENT is started/automatic - want started/automatic &green SQLWriter is started/automatic - want started/automatic &green BBWin is started/automatic - want started/automatic Name StartupType Status DisplayName MSSQLSERVER automatic started SQL Server (MSSQLSERVER) MSSQLServerOLAPService automatic started SQL Server Analysis Services (MSSQLSERVER) SQLBrowser automatic started SQL Server Browser SQLSERVERAGENT automatic stopped SQL Server Agent (MSSQLSERVER) SQLWriter automatic started SQL Server VSS Writer BBWin automatic started Big Brother Xymon Client

Include full command line in top output
by lists＠dzpconsulting.com 12 Apr '12

12 Apr '12

I'd like to change the contents of the CPU test details page to include the full command line in the top output. As I don't have my head wrapped fully around how xymon renders this data, I'm not certain where to start. I've modified the client side to include the -c option but it still looks like the client data is truncating on some default width… Any help would be appreciated. -- Michael Hobbs

Question on filesystem line processing for Windows in do_disk.c for UNC resources
