Re: [Nagios-users] checking a counter on a website
This actually hits on what I consider to be one of Nagios' (few) weaknesses. A lot of time, when I do my checks, I'm not nearly as interested in the value of a check as in the change in the value since the last check. This isa goodexample. Another itemI monitor is changes in the SNMP Interface error counters. For example, if I get more than 5 errors/second, I need to send out an alert. Finally, I have the same issue monitoring SNMP Interface statuses. But, Nagios has no feature to remember data between invocations of the checks. So, I end up storing this data in temporary files.If there was a facility to provide some information back to Nagios, and retrieve it on the next one, that would be wonderful.

Publish that value out via SNMP and then just use check_snmp to verify that the value is =1. People with more programming skills than I would probably just write one plugin to do it all.

RE: [Nagios-users] Re: Monitor DHCP Server []
There are several reasons to fail to bind a low numbered port. The most obvious is not having root privileges. If you running as root (regardless if the program is setuid root), that is not in play. The second most obvious is that something else is already listening on that port. I'd check that next.

If you do make install it will be copied to the plugin directory (usually /usr/local/nagios/libexec) and will get suid BUT as it seems you're execute check_dhcp as root in the example above (according to the '#').

RE: [Nagios-users] Nagios doesn't send mail!
Do you seeing it trying to send a notification in the log file? Perhaps you've configured it not to send emails.

Hello list, I'm using nagios 1.2 and it's working fine except the fact that it doens't send mail when servicegoes down! I can see on the web interface that the service is down (red) but I don't get emailed on my phone or email address. The mail program is working on the server, I can use command like sendmail [EMAIL PROTECTED] /tmp/testmail.txt and receive the email, I can also use /bin/mail -s to send mail via the terminal and I receive it, therefore /bin/mail and /usr/sbin/sendmail work. I know that Nagios use /bin/mail to send alert because that is what is used and configured inside the misscommand.cfg file. So I don't understand why Nagios doesn't alert me when hosts or service goes down. Somebody has an idea? Thanks.

RE: [Nagios-users] Monitor Fileserver
NetApp certainly has SNMP support. It's not wonderful, it only supports v1. As a result, it has the usual problems with overflowing COUNTER32's. But, it's fairly easy to set up and will let you monitor just about anything you want. Jason From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Hans EngelenSent: Monday, February 27, 2006 4:01 PMTo: Nagios Users MailinglistSubject: Re: [Nagios-users] Monitor Fileserver Ah, i see. Question ... is there no SNMP access for these blackboxes ? Most blackboxes do from my experience (though I usually steer clear of them so I haven't used that many of them really). SNMP access will most likely allow you to poll a fair number of interesting metrics. Free space, network utilization, load ... that kind of thing. Worth checking into should my other suggestion fail. Incidentally don't forget to give the service-user enough rights to do its work, i.e. on the share and also for other checks it might have to do or you might get other unexplained errors. Start out with adding it to the local admins group to test the general idea first (and get a baseline check)then bump it down to normal user and add rights as you need. But I am sure you know that drill.

Josh--- Hans Engelen [EMAIL PROTECTED] wrote: Dangit replied privately and not to the list, anyway heres a forward. Also just checked the /root/.smb/smb.conf reference is actually a workaround for a problem with samba's libsmbclient in the perl module Filesys::SmbClient (used by check_smb_shares.pl). Aparantly libsmbclient segfaults if it does not exist. Therefor if it does not exist the perl module Filesys::SmbClient tries to make one (an empty one) but has no permission to do so from what you wrote. I supose you could make it yourself (touch /root/.smb/smb.conf; chmod og+r /root/.smb/smb.conf). Maybe that will solve your issues with that particular check allowing you to use it to monitor the remote shares you spoke of Cheers, Hans On 2/27/06, Hans Engelen [EMAIL PROTECTED] wrote: For mapped drives that is quite normal since mapped drives are, barring a small number of special cases, only accessible for the user that did the actual mapping. It's the same problem you get for other NT services trying to access a drive mapping made from another user. Also most likely your pNSClient (or NC_Net or NSClient++) or whatever agent you have running on the Windows box is running under the System security setting. This security context is only valid for that windows box internally and as such has no credentials to access anything beyond that machine. This includes (but is not limited to) shares. Theoretically you could of course run your Nagios Agent under an actual user account, log in interactively on that same account and create a persistent mapping (net use * \\server\share /persist:yes, if memory serves) to the shares in question. Since the service will use the same profile when logging in that should solve the issue. But why even monitor a remote disk in this way. Just install the Nagios Agent on the server that houses the share and monitor it directly instead of indirectly (with all the quirks and pitfalls that come with it).Of course in this case the check_smb_shares is a solution too. As to why it insists on writing to /root/.smb/smb.conf is a bit strange. Possibly this was defined somewhere in the check_smb_shares.pl file. Open it up in a text editor and see.
