It does otherwise the central server won't know what to do with the check results that it receives. -- Start uncovering the many advantages of virtual appliances and start using them to simplify application deployment and accelerate your shift to cloud computing. http://p.sf.net/sfu/novell-sfdev2dev___ Nagios-users mailing list Nagios-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/nagios-users ::: Please include Nagios version, plugin version (-v) and OS when reporting any issue. ::: Messages without supporting info will risk being sent to /dev/null
[Nagios-users] Time period Oddity
I have run into an issue regarding time periods and I am completely stumped. I have created a time period called market-hours that goes from 9:30am to 4pm. In addition, I created a time period called market-holidays that contain a list of days that the stock market is closed. I excluded the market-holidays timeperiod from the market-hours time period. I have a series of checks that I want executed only during when the stock market is open. I added a new check into nagios, and its being scheduled for tomorrow at 9:30am. I took out the exclude portion of the market-hours time period and then the new check gets scheduled to be checked without 5 minutes of the current time. This is nagios 3.0.6 A copy of the relevant sections of the config can be found at: http://pastebin.com/me1941f5 Has anyone seen this issue before? Also, can someone explain that the difference is between "name" and "timeperiod_name"? The documentation and example config seem to both make reference to the "name" directive for timeperiod but it doesn't seem to be documented anywhere.

[Nagios-users] Alerting behavior at beginning of timeperiod
I have several processes that are started each morning from cron and then run until the early evening and are then killed. For example, every weekday at 8:00am, a daemon is started and it runs until 6:30pm. A timeperiod of this particular process has been created so between 08:00 and 18:30, nagios uses nrpe to check to make sure the process is in the process list and if not, it sends out an alert. For the most part it works exactly as expected with the exception of the alert that is thrown in the morning. I have been getting an alert each day that is timestamped a couple of seconds after 8:00am (Today was sent out at 8:00:06) My guess as to what happens is that at exactly 8am the first check is done and the process might not have been fully started, or cron started it a few seconds after the check is done. However, I have nagios setup so that normal checks are scheduled to be performed every 5 minutes. If a check fails, another check is scheduled for 1 minute after the first failed check and then if that check fails, an alert is sent out. Nagios appears to be ignoring that. My guess as to what happens is that if the first check at the start of a timeperiod fails, it immediately sends out a alert. The issue seems to have gone away after I changed the timeperiod to begin at 8:01am but I wanted to pick the brain of the community to see if this is an expected behavior or something I need to look into more closely.

Re: [Nagios-users] Alternating Notification Commands
I am trying to avoid that because it seems like it would get fairly
difficult to manage and makes
the config alot more difficult to read, especially if you happen to
have a whole bunch of
people who need to receive alerts.
But from what I can tell, this looks like the only possible solution

[Nagios-users] Alternating Notification Commands
Greetings- In addition to the two included commands for sending notifications, I defined two new ones called notify-host-by-sms and notify-service-by- sms. What I would like to do is configure nagios to have it send alerts by email during normal business hours and send alerts by sms the rest of the time. I would also like to configure certain critical services to only alert by sms regardless of the time of day. From what I can tell, there does not appear to be a straight forward way to do this because "host_notification_commands" and "service_notification_commands" are defined under "contact". It looks like I would have to create two contacts for each person, one with their email and one with their pager. Is there any way around this?
