Cleaning up history logs

What does Xymon check to determine if my history logs directory is full? After several months of not paying any attention to Xymon, I dove back in. I found that I was getting "Historical Status Log Not Avaialable". Some browsing around showed that if the log directory has less than 5% disk space available, the logs will not be written. I "df -i /home/xymon/data/histlog" directory and it was (and still) is showing 4% used. Unsure what to get rid of, I deleted everything I could find in the data directory that related to old hosts that do not exist. After doing so, log files were now available. Obviously, there was a disk space problem, but where was it? This is just a demo system so I wasn't too worried about doing such a destructive deletion of everything, however, if this were a production system I'd want to be a lot more careful as to what it is that I delete. Would I just delete everything in the histlog directory that is > X days old? -- Michael Beatty Sherwin-Williams IT Analyst/Developer michael.beatty at sherwin.com 216-515-7374

newline character needed for "xymon" command?
by Michael.Beatty＠sherwin.com 04 Dec '12

A bug maybe? I have a custom perl script that is called by clientlaunch that runs some tests. I am calling the xymon via system and passing the arguments for the alert. As an example: system("/home/xymon/client/bin/xymon 127.0.0.1 \"status+1h myhost.mycolumn yellow My stauts message\""); When the command runs, everything seems fine. Until I drill down into the history. When I go into the "Historical Status" screen for an alert, the status message is crammed in with the "unchanged in" line on the page. It looks like: *** My status messageStatus unchanged in 0.00 minutes Status message recived from 1.1.1.1 Client data available *** It doesn't happen on the main alert pages, only in the Historical Status pages. What I did to fix it, was to put a newline character at the end of all of my messages: system("/home/xymon/client/bin/xymon 127.0.0.1 \"status+1h myhost.mycolumn yellow My stauts message\n\""); The newline corrects the formatting on the alert message and it displays property, however, I'm not sure this should be like this. Is the newline character supposed to be necessary?

Try running this as the xymon user, to find out where it's looking for the file: HOME=~xymon sudo -u xymon xymoncmd strace -f mysql 2>&1 | grep ^stat On my system: stat("/etc/my.cnf", 0x7fff9cbc1830) = -1 ENOENT (No such file or directory) stat("/usr/lib/xymon/.my.cnf", 0x7fff9cbc1830) = -1 ENOENT (No such file or directory) stat("/etc/my.cnf", 0x7fff9cbc1830) = -1 ENOENT (No such file or directory) On 30 November 2012 00:43, Leon Volfson <leon at one.co.il> wrote: > Hi Mike, > thanks for answering, > I did run the "whereis xymon-client" and I do know about this directory. > unfortunately, putting the file there doesn't do anything. > > > Lenny > > > On Thu, Nov 29, 2012 at 2:50 PM, Mike Burger < > Mike.Burger at freedommortgage.com> wrote: > >> Oops…client…if you installed it from RPM, the home dir is likely >> /usr/share/xymon-client.**** >> >> ** ** >> >> *From:* xymon-bounces at xymon.com [mailto:xymon-bounces at xymon.com] *On >> Behalf Of *Mike Burger >> *Sent:* Thursday, November 29, 2012 7:49 AM >> *To:* Leon Volfson; xymon at xymon.com >> *Subject:* Re: [Xymon] mysql password file on centos 5, xymon client**** >> >> ** ** >> >> Leon,**** >> >> ** ** >> >> If you installed Xymon from RPM on your CentOS 5 system, and you run >> either “finger xymon” or “grep xymon /etc/passwd”, you’ll likely note that >> the xymon user’s home directory is /usr/lib/xymon.
