All,
I've run into a bit of a problem with my understanding of how metrics are
created. We have a configuration where a number of hosts (mixed windows /
Linux) send data to a Linux host. This linux host is then configured as the
collector for a cluster in my gmetad.conf file:
data_source "My Cluster" 1.2.3.4
In my gmond config file on my Windows host, I have the following:
collection_group {
collect_every = 40
time_threshold = 180
metric {
name = "sys_cpu_queue_len"
value_threshold = 1.0
}
metric {
name = "mem_pages_sec"
value_threshold = 1.0
}
metric {
name = "mem_committed_bytes"
value_threshold = 1.0
}
metric {
name = "phys_disk_bytes_sec"
value_threshold = 1.0
}
metric {
name = "phys_disk_time"
value_threshold = 1.0
}
I don't see the phys_disk_bytes_sec or phys_disk_time in the web UI and I don't
see RRD files with names like this under /var/lib/ganglia/rrds/My Cluster/
Can anyone please advise what step I've missed in getting these metrics from
the host to my web frontend ?
I did try adding these metrics to the gmond.conf on the Linux collecter node,
but it complained about not knowing about these - does the collector need to
know about all metrics for all hosts that report to it ?
