[Ganglia-general] Error 1 sending the modular data
So for background, my original problem is that load_one will not be updated by gmetad for a period of over 600 seconds (an arbitrary timeout signifying that gmond/the host is probably down). It occurs a few times/day across hundreds of hosts, and often occurs near midnight localtime. This *appears* to correlate with messages along the lines of the following (I didn't see anything else suspicious in syslog): Aug 12 23:53:26 adq82 /usr/sbin/gmond[28637]: Error 1 sending the modular data for entropy_avail#012 Aug 12 23:59:00 adq82 /usr/sbin/gmond[28637]: Error 1 sending the modular data for mem_cached#012 Aug 12 23:59:10 adq82 /usr/sbin/gmond[28637]: Error 1 sending the modular data for diskstat_sda_write_bytes_per_sec#012 Since it occurs infrequently running in debug mode on every server is not a good option. But false positives that keep people from sleeping are bad. First of all, does a correlation between these messages and all metrics not reporting for a period of time make sense? If not what should I be looking at? Second, if this is anything other than a red herring, I'm totally confused how to debug it. Even if debug was enabled the debug message [1] does doesn't seem to include any additional information. Also 1 seems like it could be two different errors [2] [3].

[Ganglia-general] gmetad xml generation time
I have a process that periodically polls gmetad (builds models of some metrics, alerts if things don't look like). To reduce the number of variables I set up a dedicated gmetad on the same host as the poller and set write_rrds off. Unless I'm missing something the only thing it should be doing is polling gmond, and responding to my polls. Polling localhost currently has a mean around 2000 ms, with a stddev around 30. I've seen higher outliers, but right now I'm just trying to figure out of that's normal. 2000 ms to send a request over the loopback interface *seems* like a lot. But I don't really have anything to compare it to. Is that normal? Info: - ganglia 3.4.0 - centos5 [1] - xml size: 25 MiB - hosts: 300 - metrics: 9k - unique host-metric pairs: 80k [1] Same setup in another DC with centos6, so I don't think it's that. -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

[Ganglia-general] CPU Steal not logging yet enabled
Hello,
I have enabled CPU Steal monitoring on my AWS EC2 servers by adding the
following to my gmond.conf:
metric {
name = cpu_steal
value_threshold = 1.0
title = CPU steal
}
but I am not getting any CPU steal information. Any idea what I am
missing? Version is:
Ganglia Web Frontend version 3.4.2
Ganglia Web Backend *(gmetad)* version 3.3.7
Thanks
Zuhaib
