Cacti

Alright. Barking up the snmpv2 tree: I added an old community string to the switch config. Spine started polling correctly on SNMPV3. Now, I'm pretty sure snmpv3 doesn't NEED community strings, but whatever. Just to check, I REMOVED the community string from the switch config. SPINE CONTINUED TO WOR...

OH MAN IT'S GETTING WORSE.

After all the various tweaks I've made, now snmpv2c DOES work. Unfortunately this isn't really acceptable, since we're spitting traffic over the internet and encryption is required.

So why would snmpv3 work sometimes, but not other times?

Since this is SUCH a popular thread, some updates: The 'lol nothing will graph' turned out to be a timezone issue - the guy that set this up originally was on the East Coast, so the php.ini was set to his timezone. When I jumped between cmd.php and spine, a everything was updated according to east c...

Everything I do seems to be one step forward, two steps back. :( I find now that switching to cmd.php and then back to spine has effectively turned off ALL graphing. What. Graphs simply do not update. I've turned logging up to debug, and there seem to be no errors - spine correctly snmpwalks, correc...

More updates for those following along: -There are other switches on the network with higher uptime. -Switching to cmd.php instead of spine DOES register the device as up (however, it breaks damn near everything else - every data source has a 'partial result', so this isn't really a viable option). ...

NOPE. So, no luck. I'm more and more sure that this uptime OID, .1.3.6.1.2.1.1.3.0 , is the problem. I can snmpget it no problem from command line, but it's way over 1e9 timeticks. When poller.php tries to get the thing, it returns "U." Guys... it's way over ONE HUNDRED FORTY FIVE DAYS. SU...

Thanks for the idea! I have tried this, but alas, no luck. I've even re-entered all the snmp setting in both the switch config and cacti, and double/triple checked them by snmpgetnexting from CLI. Either way, the 'bad' device is configured the same as the 'good' device... and when I switch the hostn...

So, uh, SNMP ping should work, right?

I'm sorry, additional information:

cacti is currently 8.8b
rrdtool is 1.3.8
running centos 6.7

halp!

Hi! I inherited a very messy cactiEZ system a few weeks back, and I've been up and down the documentation (and this forum) for eons getting everything we need sussed out. Thanks to the very useful information on this forum (and the multitudes of people having similar problems to mine), I have manage...
