Hello,
I have a question which may or may not be a bug. I have a number of nodes
running gmond 3.1.7. All of these hosts are configured to unicast to a single
server via udp:
udp_send_channel {
host = 192.168.1.100
port = 8649
}
This server is configured to received udp
udp_recv_channel {
port = 8649
}
tcp_accept_channel {
port = 8649
}
this configuration works well, data is collected and stored in rrd. I am
using
a script to connect to the TCP port and pull the XML description of the cluster
state. This works fine - except when the server gmond is restarted. In this
case the server gmond comes back up and receives data from the clients - but
does add the metrics back to the XML description, instead I have XML host entry
with no metrics. I have left it running in this state for 24 hours with no
update to XML metric information.
Example (no XML metric data)
<GANGLIA_XML VERSION="3.1.7" SOURCE="gmond">
<CLUSTER NAME="Dev" LOCALTIME="1305125947" OWNER="unspecified"
LATLONG="unspecified" URL="unspecified">
<HOST NAME="test1.test.com" IP="192.168.1.121" REPORTED="1305125936" TN="10"
TMAX="20" DMAX="0" LOCATION="unspecified" GMOND_STARTED="1305062306">
</HOST>
<HOST NAME="test2.test.com" IP="192.168.1.122" REPORTED="1305125937" TN="10"
TMAX="20" DMAX="0" LOCATION="unspecified" GMOND_STARTED="1305062306">
....
</HOST>
</CLUSTER>
</GANGLIA_XML>
after restarting a gmond client, the XML descriptions are updated for that node
on the server.
<HOST NAME="test1.test.com" IP="192.168.1.121" REPORTED="1305126101" TN="4"
TMAX="20" DMAX="0" LOCATION="unspecified" GMOND_STARTED="1305126101">
<METRIC NAME="mem_total" VAL="2059524" TYPE="float" UNITS="KB" TN="2"
TMAX="1200" DMAX="0" SLOPE="zero">
<EXTRA_DATA>
<EXTRA_ELEMENT NAME="GROUP" VAL="memory"/>
<EXTRA_ELEMENT NAME="DESC" VAL="Total amount of memory displayed in KBs"/>
<EXTRA_ELEMENT NAME="TITLE" VAL="Memory Total"/>
</EXTRA_DATA>
...
looks like a gmond 'server' restart requires clients to restart to get XML
metric information. Is this by design or a bug?
Thanks
Kevin
