[jira] [Created] (AMBARI-13336) Flume agent specific metrics not
showing up as graphs
Dmytro Sen created AMBARI-13336:
-----------------------------------
Summary: Flume agent specific metrics not showing up as graphs
Key: AMBARI-13336
URL: https://issues.apache.org/jira/browse/AMBARI-13336
Project: Ambari
Issue Type: Bug
Components: ambari-metrics, ambari-server
Affects Versions: 2.1.2
Reporter: Dmytro Sen
Assignee: Dmytro Sen
Priority: Critical
Fix For: 2.1.3
After creating a Flume agent with below configuration, I selected the host in the agents table of Flume service summary page. I was expecting graphs of metrics to show up for that host, but I dont see any graphs.
{noformat}
# Name the components on this agent
a1.sources = r1
a1.sinks = k1
a1.channels = c1
#
# # Describe/configure the source
a1.sources.r1.type = netcat
a1.sources.r1.bind = localhost
a1.sources.r1.port = 44444
#
# # Describe the sink
#a1.sinks.k1.type = logger
a1.sinks.k1.type = hdfs
a1.sinks.k1.hdfs.path = /tmp/events_a1_%y-%m-%d/%H%M/%S
a1.sinks.k1.hdfs.filePrefix = events-
a1.sinks.k1.hdfs.round = true
a1.sinks.k1.hdfs.roundValue = 1
a1.sinks.k1.hdfs.roundUnit = minute
a1.sinks.k1.hdfs.useLocalTimeStamp = true
#
# # Use a channel which buffers events in memory
a1.channels.c1.type = memory
a1.channels.c1.capacity = 1000
a1.channels.c1.transactionCapacity = 100
#
# # Bind the source and sink to the channel
a1.sources.r1.channels = c1
a1.sinks.k1.channel = c1
{noformat}
The reason graphs are not getting created is the below GET call which should return (from Ambari-1.7.0)
{code}
{
"href" : "http://gs170-1:8080/api/v1/clusters/c1/hosts/gs170-3/host_components/FLUME_HANDLER?fields=metrics/flume/flume/CHANNEL/*&_=1443160542629",
"HostRoles" : {
"cluster_name" : "c1",
"component_name" : "FLUME_HANDLER",
"host_name" : "gs170-3"
},
"host" : {
"href" : "http://gs170-1:8080/api/v1/clusters/c1/hosts/gs170-3"
},
"metrics" : {
"flume" : {
"flume" : {
"CHANNEL" : {
"c1" : {
"ChannelCapacity" : 1000.0,
"ChannelFillPercentage" : 0.0,
"ChannelSize" : 0.0,
"EventPutAttemptCount" : 0.0,
"EventPutSuccessCount" : 0.0,
"EventTakeAttemptCount" : 99.0,
"EventTakeSuccessCount" : 0.0,
"StartTime" : 1.4431597139E12,
"StopTime" : 0.0
}
}
}
}
}
}
{code}
but instead returns without the channel name:
{code}
{
"href" : "http://c6401:8080/api/v1/clusters/c1/hosts/c6402.ambari.apache.org/host_components/FLUME_HANDLER?fields=metrics/flume/flume/CHANNEL/*&_=1443161204742",
"HostRoles" : {
"cluster_name" : "c1",
"component_name" : "FLUME_HANDLER",
"host_name" : "c6402.ambari.apache.org"
},
"host" : {
"href" : "http://c6401:8080/api/v1/clusters/c1/hosts/c6402.ambari.apache.org"
},
"metrics" : {
"flume" : {
"flume" : {
"CHANNEL" : {
"ChannelCapacity" : 1000.0,
"ChannelFillPercentage" : 0.0,
"ChannelSize" : 0.0,
"EventPutAttemptCount" : 0.0,
"EventPutSuccessCount" : 0.0,
"EventTakeAttemptCount" : 8.0,
"EventTakeSuccessCount" : 0.0,
"StartTime" : 1.443127087019E12,
"StopTime" : 0.0
}
}
}
}
}
{code}
Due to this reason no metric graphs are created and the sections are empty.
