http checking return "DNS error" message
list T.J. Yang
Recently I have a DNS servers change on hobbit server. Ever since then http service checking are Tue Jul 29 14:56:47 2008 So far I have done following. 1. make sure dns is in /etc/nsswitch.conf host entry. 2. ping terminal.sub.test.com works. 3. /etc/resolv.conf is configured with new dns servers and their ips. 4. clean out "/var/opt/hobbitserver42/tmp/*..status files and restart hobbit server. Is there any better way to debug the issue ? 1. Example error message. Wed Jul 30 07:50:51 2008: DNS error http://terminal.sub.test.com/ - DNS error Seconds: 0.00 2. The batch http checking showing flip-flop on all the machines with http checking.

Hi all
Interesting problem here.
Trying to graph some data.
Output is all OK, test looks good, some information appears, and
somewhere in the status are the single lines
Data1=value1
Data2=value2
All good.
Problem though, in the status text that appears on the screen, there are
some colons. :
As we all know, the ncv module can use information in the form
Data1=value1 Or Data1 : value1
So it's interpreting those lines with the : as graph data, and trying to
stick it into the rrd file, with somewhat tragic results.
Any idea how to convince the ncv graphing module to ignore the : as a
data seperator, and only look at = ?
Cheers
Vernon

Why not pre-process the data before it gets to hobbit and remove the ":"'s? Phil 2008/7/31 Everett, Vernon <user-9da1a1882f49@xymon.invalid>:

We can do that, but I was hoping not to. The info is ip:port, which is traditionally displayed with a : If we have to, I will.
