Cactid frustrations

Post by Garp »

After some fun with Ubuntu and its cacti repositories I know in future I will be manually compiling and installing cacti if I ever have to do it! At least that way I'll be more confident about how exactly its setup.

I've replaced an old BSD based dying server with a nice shiny new Ubuntu based one. Unfortunately Cactid refuses to run properly on this box. Following some comments on here about issues with the default repository build (0.8.6f) I've downloaded and compiled my own of 0.8.6i.. unfortunately this still comes up with the same issue.

I think I know whats going on and it relates to no longer existant interfaces / SNMP devices on the switch in question.

an output from tcpdump is what started to cause suspicions in this regard (I've removed sensitive data):

:/usr/share/cacti/site# tcpdump -ieth0 -n port snmp
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth0, link-type EN10MB (Ethernet), capture size 96 bytes

This is using my custom build of cactid. It returns the following (again confidential data removed):

/usr/local/cactid/bin/cdb# /usr/local/cactid/bin/cactid --verbosity=DEBUG 79 79
CACTID: Using cactid config file [/etc/cactid.conf]
CACTID: Version 0.8.6i starting
CACTID: Host[79] DS[6063] WARNING: SNMP timeout detected [50000 ms], ignoring host '<remote-switch>'
CACTID: Host[79] DS[6072] WARNING: SNMP timeout detected [50000 ms], ignoring host '<remote-switch>'
CACTID: Host[79] DS[6073] WARNING: SNMP timeout detected [50000 ms], ignoring host '<remote-switch>'
CACTID: Host[79] DS[6074] WARNING: SNMP timeout detected [50000 ms], ignoring host '<remote-switch>'
CACTID: Host[79] DS[6075] WARNING: SNMP timeout detected [50000 ms], ignoring host '<remote-switch>'
CACTID: Host[79] DS[6076] WARNING: SNMP timeout detected [50000 ms], ignoring host '<remote-switch>'


Yes.. I know 50,000ms is a rather large figure I was trying to confirm my suspicions.

It produces that result very quickly and then stops, so it seems like if it doesn't get a happy response back from the switch, even though the switch is alive, cactid stops? I would guess this was put in with the intention that Cactid wouldn't waste time polling a dead device? Its not exactly dead, it is actually responding to the poller, it just doesn't have any data for those interfaces any more! :D

I really would like to get this working and shift away from cmd.php if I can!


If anyone has any suggestions on how to clean up the switch I'd love to hear them too.. I'd really rather avoid deleting and re-creating the switch if at all possible, as I'd like to keep all the history for the interfaces.

Hmm, that's quite odd. Can you please download and build the SVN version of the product (BRANCH_0_8_6) and then can we do an online "GotoMeeting" conference sometime Thursday?

I am in the Eastern Time Zone. Detroit, MI. What do you think? This is definately a bug, but I would like to do this live.

I'm trying to use the SVN build of the cactid, but its failing on make?

Makefile syntax isn't something I've delved into to be honest!



The commands I ran:

Code: Select all

svn checkout svn://svn.cacti.net/var/svnroot/cacti/branches/BRANCH_0_8_6
cd /BRANCH_0_8_6/cactid
aclocal
autoconf
./configure
make
Which returns:

Makefile:204: *** missing separator. Stop.

*shrug*

Same occurs from a "make install"

Line 204 for me reads:
@AMDEP_TRUE@@am__include@ @am__quote@./$(DEPDIR)/cactid.Po@am__quote@

I've attached a copy :)

Okay, I finally got a chance to look at this further.

Grabbed the SVN version, ran the bootstrap, configured, compiled and installed it.

root@<server>:/home/<user>/BRANCH_0_8_6/cactid# /usr/local/cactid/bin/cactid -v
CACTID 0.8.6i Copyright 2002-2006 by The Cacti Group

Okay, so thats good (I hope). The apt version gets installed elsewhere.

root@<server>:/home/<user>/BRANCH_0_8_6/cactid# /usr/local/cactid/bin/cactid --verbosity=DEBUG 79 79
CACTID: Using cactid config file [/etc/cactid.conf]

CACTID: Host[79] DS[6076] WARNING: SNMP timeout detected [50000 ms], ignoring host 'remote.host'
CACTID: Time: 1.4180 s, Threads: 8, Hosts: 2

It looks like the latest SVN version of CACTID does the same as the released version of CACTID *shrug*

just running CACTID without locking it down to that specific host I know came up with an error last time and I can see that CACTID will poll devices succesfully, it does still seem to come down to that if the first thing it polls isn't active, even if it gets a response back from the remote device it gives up. It certainly doesn't reach that deliberately stupidly high timeout :D

OIDs Per SNMP Get Request

Post by disirk »

I was seeing this exact same thing on various platforms...Netscaler, SonicWall iNOC, Foundry ServerIrons, and yes...CatOS...

My fix was to keep backing down my OIDs per SNMP Get Request until they all vanished. Now I run the following:

Concurrent Processes: 4
Max Threads: 15
PHP Script Servers: 4
Timeout: 5
Max SNMP OID's Per SNMP Get Request: 20

Had it at 30, but Netscalers didn't like that...
