I would need a lead on how to shutdown several virtual machine on our ESX server. We put in place a UPS and now we want to implement a automatic shutdown of the VMs (in a certain order) when our UPS battery goes under the threshold. I do monitor already the battery state. So I just need to put in place the eventhandler. How to proceed?
View 1 RepliesI have placed the restart-ssh script in /usr/local/nagios/libexec/eventhandler but its not working on seeing the event log the following information is obtained
Though i have checked the script manually by the following command
It works fine with both of the above mentioned commands
I don't know why it is not able to restart ssh when nagios is calling it as event handler
The service definition for ssh in localhost.cfg is as follow:
Error: Cannot open log file '/usr/local/nagios/var/archives/nagios-07-08-2011-00.log' for reading!

I have installed a cluster computer with 10 nodes . The manufacturer is HP . All nodes and the master node have redhat enterprise linux installed in them . When I shutdown the nodes from the master terminal using "shutdown -h now" they get shutdown . But they dont get completely turned off . This issue bothers me when the power supply is given , all nodes boot up simultaneously generating a huge heat .
Thing to note : When we shutdown our PC they get completely turned off . When the power supply is given , a press on the Power On button is required to boot the system. But , why does it not happpen in the case of cluster? Is there any other way of completely turning off the nodes from the master terminal ?

View 3 Replies View RelatedThe previous version of one of my websites was static and so the URLs looked like this: [url]
A few months ago I re-did the site to be completely dynamic. There are no individual pages for product reviews, just one which pulls the right data from a database. So now, my URLs look like this: [url]
Some fellow ex-googler who specialize in SEO told me that the previous URL scheme was better for search engines because it had the product name. Of course, I have set up redirects from the old naming scheme to the new one but what I would like to do is have 'review.php' handle the request for 'review_XXXX_YYYY.php' without actually doing a redirect... and do this for past and future products. I don't want to have to actually create all these 'review_XXXX_YYYY.php', there would be hundreds, just make it seem like they exist to visitors.
Can we use static thread handlers ?

I like to set firefox to ask me every time what to do when downloading a file. This works well if I want to save to disk, but if I want to use an application I don't get a dropdown with applications to choose, but a browse button which requires the application to be typed every time. To make it a bit clearer, if I have clicked on a pdf file I get this: [URL]. How do I get okular listed in a dropdown instead of the browse button?

View 1 Replies View RelatedThis is an odd question, but I can't figure out why my nagios emails aren't being sent. In fact, I got my last one three days ago so it *should* be working.
I have everything in contacts.cfg, and the admin page tells me that the following should be sent: Unknown, Warning, Critical, Recovery, Flapping, Downtime
I also have notify-service-by-email and notify-host-by-email.
I have no idea if nagios emails just don't want to be sent or what -- and I'm not even sure if the nagios emails are even trying to be sent.
Here's my contacts.cfg code...
There's nothing in /var/log/nagios besides the mention of that email address in objects.cache, so I have no idea if an email was attempted to be sent. My sendmail queue is empty as well.
Meanwhile, I have some downtime on a service and didn't get notified. Only the web interface is helping me out here. Any ideas why I am not getting email? How can I run a test to see if everything's working okay?
When I try to log into the webgui I am getting a file to download labled "nagios". When double-clicking the file I get the error " The file /path/to/file cannot be found. Please check the location and try again".

View 1 Replies View RelatedOperating System: Ubuntu 11.04 w/ Unity-2D
I had serveral custom url-handlers setup using gconftool-2 in my old Ubuntu 10.10 setup, but now after reinstalling and updating to Ubuntu 11.04 I can't get a single one to work with Chrome (11.0.696.57) nor other browsers like Midori.
The only solution was to switch to Firefox and setup them manually using network.protocol-handler*
It seems (on the surface) that Chrome insists on opening the links with xdg-open (and if I remember correctly in Ubuntu 10.10 Chrome said it opened the links using the apps set in gconf), but xdg-open only supports the most common http* and ftp* does it not? - Just learned that xdg-open is the default handler for all urls.
I've tried everything, including searching through Chrome's config files, reinstalling Chrome, and tested changing the paths to my apps - but without any luck.
Note that I'm talking about links in Google Chrome, Firefox on the other hand doesn't even check the url-handlers so I had to set them up manually using about:config > network.protocol-handler*
So they work in Firefox when added, but in no other browsers.
Google Chrome opens the links with xdg-open [url] as depicted in the attacheds screenshot, but this throws in error, found in .xsession-errors:
Code:
gvfs-open: svtrip://example.com/: error opening location: The specified location is not supported
