That's what I thought at first as well, then noticed the issue happening with monitoring the localhost, including the ping response time.  Looking at all the graphs, the gaps seem consistent across everything so it's like everything works or everything doesn't.  I would assume that something intermittent would allow some hosts or oids to work and some do not.  Very odd.  My sysadmin skills aren't great but I'll keep poking.

Attached is the log for running  sudo ./poller.php -d -h localhost | tee ~/log4.txt

Thanks for all the effort!

The fact that you get any data at all suggests that it's not a code issue.

The graph looks exactly how i'd expect for something where the snmp queries are imtermittently failing, either because of poor network or something like a firewall with constrained sessions.

Have you tried running the poller in debug mode and seeing what output you get?

Hi all,

  Yesterday afternoon I added several devices and since then I'm
getting gaps in *all* my graphs.  Even those for the localhost.  I
upgraded to the latest (commercial) version, just to check, and still
having issues.  I'm not quite sure what to make of this.

  I have nfsen and cacti running on the same box and their graphs all
look ok so it seems something specific to observium.  My disk io is a
bit high but not too bad, cpu is good, ram is fine.  See attached
screen shot for example of gaps.

8gb of RAM
Ubuntu 12.04
750gb sata disk (ST3750640NS)
Intel(R) Xeon(R) CPU           X5450  @ 3.00GHz

*couple of notes*

- a few days ago I tweaked some mysql settings

< #table_cache            = 64
---
table_cache             = 600
65c65
< query_cache_size        = 16M
---
query_cache_size        = 32M

- Also in order to group some devices together I manually edited the
observium.device.location column in the db for some of the devices.

Thoughts?  Direction?

Thanks all!
