Re: [Nagios-users] How often does Nagios need restarting? (Quis custodiet ipsos custodes?)
Jamie, Sorry for the very tardy response - it's been busy. Two responses to all your good comments: 1. The problems with Nagios slacking on the job were confirmed by the Nagios administrator. Permanently, he is looking to move the setup to a box with more memory (it is currently a Red Hat box). Temporarily, he talked about using cron to restart it every night. Since it's been more responsive lately, I have a feeling he has done just that. I did ask if he thought whether upgrading the NSClient would help, since we are currently using NSClient++ 0.3.1 and NSClient++ 0.3.6 was just released, but while encouraging me to try out 0.3.6, he feels memory constraints on the current box is the cause of the problem and nothing else. I didn't post any configs files because I am not the Nagios administrator and don't have access to the configs or the box itself except for what I am allowed to see for our hosts via http. Thanks for letting me know 2.9 is relatively stable and that it, in all likelihood, is not the cause of the problem. 2. Thanks for pointing out that host checks are not always performed unless a service has been detected has failing. I value the service checking, but I assumed it was also pinging the host on a regular basis and that is apparently not the case. I come from the background of using products such as Insight Manager and OpenManage which are vendor-specific solutions that have their limitations but which automatically perform pinging on a regular basis. I'll look at the documentation for information on getting that set for us. It explains my frustration as to why a server can reboot and Nagios not detect it. Thanks again for taking time.

You should really look at your current config files and read the manual on 2.9, or upgrade to 3.x and again rtm... Also, you have not sent anything specific related to your problematic config(s) for anyone on this list to even guess either way whether or not something is mis-configured. If you are concerned about posting your configs/setup, change stuff properly to hide what you need to on-list. (I apologize if I have missed your earlier posting.

[Nagios-users] Last check info seems stale (Nagios 2.9)
I am a Nagios user, not the administrator. We are running Nagios 2.9 on RHEL 4 or 5. Overall, 200+ hosts with 3000 services being monitored, but I have access for monitoring a smaller number of hosts. In looking last week into an issue where a host had gone down but no alert was sent, I noticed that on the Host Status Details For All Host Groups screen, where it lists Hosts, Status, Last Check, etc., the Last Check date for some of the hosts went back almost two months. I pointed this out to the administrator who didn't disagree with my statement but said the logs showed otherwise. Nagios was restarted but even now, there is a host where the Last Check date still shows as 05-19-2009. There are other hosts showing a last check date of June 5, June 9, June 10, and so on. These hosts are definitely up. Either Nagios is being tardy at checking things, is *not* being tardy but is displaying inaccurate information, or I am misunderstanding this field or what Nagios means by Last check. Can anyone shed some light?

[Nagios-users] Nagios and Windows DFS replication
[Disclaimer: I am not the Nagios administrator, just an end-user] We are using DFS-R on a number of Windows servers. Nagios is already being used to monitor these servers (NSCLIENT++ 0.3.1). It is possible to schedule some tasks to run a DFSRDIAG or DFSRADMIN report on the status of the replication folders and e-mail the results, but I am wondering if anyone is using Nagios to monitor DFS-R and, if so, how.

[Nagios-users] After switching to Nagios 2.9, Nagios Checker always asking for credentials
Disclaimer: I'm a Nagios user, not the administrator. * Problem: When I was using the Nagios Checker version .13 against our old Nagios 1.2 system, there were no problems. However, since switching to a newer Nagios 2.9 system, Nagios is always asking for credentials whenever it wants to check. If I have configured Nagios to check five minutes, I am asked every five minutes for credentials. * This has apparently been bugged at http://code.google.com/p/nagioschecker/issues/detail?id=56colspec=Stars %20ID%20Type%20Status%20Priority%20Summary%20Opened%20Modified%20Closed. However, this does not mean that the problem is ultimately in the plug-in itself. Perhaps I need to configure things differently. Does something need changing on the Nagios box itself? * I have tried various modifications of Nagios Checker configurations to resolve the issue but with no luck. Somehow, Nagios used to cache my credentials but isn't now, perhaps?

[Nagios-users] Monitoring ARCserve services
[Note that I am a Nagios end-user, not the administrator. Someone at HQ runs the box.] We currently use Nagios 1.2. We have a Windows Server 2003 server running the latest ARCserve (11.5 SP3). We have basic monitoring of the box via Nagios but are looking for a way to monitor the ARCserve-specific services, including: [Running]CA BrightStor Database Engine [Running]CA BrightStor Discovery Service [Running]CA BrightStor Job Engine [Running]CA BrightStor Message Engine [Running]CA BrightStor Service Controller [Running]CA BrightStor Tape Engine [Running]CA BrightStor Domain Server This is not about an ARCserve trap for detecting failed jobs. Rather, we just want to be alerted when these specific services go down or up. Any suggestions? What could I pass on to our Nagios admin?
