Unix Agent
by Ryan Milton 23 Dec '13

23 Dec '13

Still not quite understanding Unix Agent--- from the sounds of it, it has to be installed on all servers that Observium monitors? I finally have SNMP running on FreeBSD, OpenBSD, and from the FAQ's, etc, it really seems that I should bypass Net-SNMP with Observium. Regards, Ryan Milton

Network Dependencies
by Johnathon Voegeli 22 Dec '13

22 Dec '13

Hey guys, I am using the beta version of observium updated with svn with the server running in a datacenter in one US state and some of the SNMP agents in several others. It works perfect with one site, however the other has terrible internet connecting the site, and we lose vpn every once in a while. It immediately comes back, however when it polls while the site is down we receive 20-30 emails about devices being down when in fact it is the internet connection. Is there a way (or a plan in the future) to set dependencies on polling? For example if the Router/Modem does not respond then send an alert as down, but it knows that in fact if it can't talk past the router then obviously the rest will show as down as well so the alerts won't bombard our email? ~JV Johnathon Voegeli jvoegeli(a)voigtie.com<mailto:jvoegeli@voigtie.com>

Skip Memory Pools by regex
by Robert Williams 21 Dec '13

21 Dec '13

Hi, Can anyone tell me if it's possible to 'skip' polling of memory pools using their names (or regex) like you can with interfaces? I need to remove the "reserved" and "image" memory pools which are detected on all of our ASR9k units as they are all 100% (by nature) so are always red. Example below/attached: It's probably staring me in the face but despite trawling the config options I cannot see one for memory pools - Any ideas? Cheers!

Auto Discovered Device
by Matthias Cramer 20 Dec '13

20 Dec '13

Hi All In my Observium installation there is a new Device named "core" appearing every 6h (expect from the discover process) after 12h I have two of them and so on. If I delete them the reappear. I do not know from where this comes. Is there any way to find out how observium finds this device? If not, what's the best way to prevent Observium from automatically adding new devices ?

Email Alerts with Mail/Sendmail Not Working
by sysadmin＠boyah.net 19 Dec '13

19 Dec '13

Hello, I'm having an issue getting Observium to send email alerts. 1. SysContact is set on the client device. 2. Sending test mail from monitoring server via sendmail on command line works fine. 3. Observium config.php has following configuration: $config['alerts']['email']['enable'] = TRUE; $config['alerts']['port']['ifdown'] = TRUE; $config['alerts']['email']['default'] = "notif…(a)xx.net"; $config['email_backend'] = 'mail'; $config['email_from'] = "MTR <mtr...(a)xx.net>"; $config['email_sendmail_path'] = '/usr/sbin/sendmail'; $config['alerts']['interval'] = 900; Setup a demo device, ensured it was polling and reporting correctly, then force-shutdown the demo. No mail sent by Observium. In mail.log, nothing reported (except for the successful test message I sent via command line). Maybe I'm misunderstanding. Will Observium send an email alert when a monitored device goes down, when configured this way? How can I achieve this? Many thanks in advance to anyone who can offer advice.

NFSEN Integration Issues
by Brian Morgan 17 Dec '13

17 Dec '13

Hello, The recent netflow question, reminded me that I needed to finish configuring nfsen on our box. I started going through the process of configuring observium, but no matter what I put in the config file, the suffix would not be removed. Digging into the code it looks like the logic was there in the /html/includes/functions.inc.php to check and use strstr to remove the domain name. But the string that was created was never actually used to open the rrd file. I have updated our functions.inc.php to use $nfsen_filename instead of $basefilename_underscored when creating the $nfsen_rrd_filename variable and the integration is now working. Who should I reach out to discuss our small changes to functions.inc.ph in regards to nfsen integration? Also is it okay to share code snippets of the latest svn branch on this list? Thank you, Brian
