Grettings all, hopefully someone has seen this before and can offer
some assistance.
I have a primary zenoss server and a remote collector.
When browsing to the "Status" or "OS" tab of the remotely collected
device, the website is very slow. Maybe 2-3 minutes to pull up the
webpage.
All other devices (collected on the primary) are fast.
All other tabs (Events, Edit, Perf, Hardware, Software) for the
remotely collected devices are fast.
Pulling up a specific interface (once you do get to the OS tab) is
fast.
Graphs come from the remote collector are returned in a second or two.
I do have a low bandwidth, high (40ms) latency, connection between
the 2 hosts.
I don't think it's an issue on either server -- load, cpu, memory,
disk all look good.
I don't know if it's a zenoss problem, or a network problem. Or a
combination. I don't think it is network because a TCPDUMP on the 2
hosts (and to the device being collected) does not seem to show alot
of traffic.
Servers are quad-core with 8GB ram each, SAS disks. The primary
collects about 1400 devices, the remote collects about 50 for now,
with plans to collect maybe another 200.
If you have any pointers of where I should look, please let me know.
Thanks again for any insight.
The fact that this problem is on the Status and OS tabs makes me think
it has to do with pulling performance data from your remote collector
to you central. I saw this because to show the "Uptime" on the status
tab takes an XML-RPC call to the collector from the master, as well as
all of the file system utilization information on the OS tab.
Do you have zopectl or zenrender running on the collector? What is the
render URL on the collector's edit tab?
