Hi,
I have the same issue and any help will be appreciated. I have looked up
archives, but have been unable to resolve it.
I installed ganglia3.1.7. The
collector gmond starts up and I see the host
as "up" for sometime and then the
host goes down. I ran gmond with debug=9 and redirected it to a log.
I don't see
any errors. In fact, I do see these messages coming into the
log even after the
host is being reported as down which means gmond is running :
" metric 'lwrite_sec' has value_threshold 1.000000
metric 'phread_sec' being collected now
metric 'phread_sec' has value_threshold 1.000000
metric 'phwrite_sec' being collected now
metric 'phwrite_sec' has value_threshold 1.000000
sent message 'heartbeat' of length 52 with 0 errors
Processing a metric value message from machine1
Got a heartbeat message 1298316893
"
1. I am unable to telnet:
telnet localhost 8649
Trying ::1...
telnet: connect to address ::1: Network is unreachable
Trying 127.0.0.1...
2. Telnet to port 8651 works and sends an xml. I notice TN>TMAX in the XML if
that means anything (as I read in some other thread):
TN="21416" TMAX="180"
3. `gstat -a` hangs
4. The only difference I see in gmond log and I am not sure
if that is expected
behavior is that, initially there are messages like and
they are no longer there:
"saving metadata for metric: phwrite_sec host: machine1
Processing a metric value message from machine1
***Allocating value packet for host--machine1-- and metric
--phwrite_sec-- ****
"
I am running the simplest config of one gmetad and
gmond on the same machine
(SunOS). I am using default multicast config.
udp_send_channel {
#bind_hostname = yes # Highly recommended, soon to be default.
# This option tells gmond to use a source address
# that resolves to the machine's hostname. Without
# this, the metrics may appear to come from any
# interface and the DNS names associated with
# those IPs will be used to create the RRDs.
mcast_join = 239.2.11.71
port = 8649
ttl = 1
}
/* You can specify as many udp_recv_channels as you like as well. */
udp_recv_channel {
mcast_join = 239.2.11.71
#family = inet4
port = 8649
bind = 239.2.11.71
}
Thanks for helping,
