dougszsameer: I don't have any specific help for you, but as a general approach it's worth breaking the problem up. No metrics showing? Are they in your time series database? Not there? Check that they come in via the Monasca API logs...10:41
dougszYou might also try tailing the Monasca API as you create the alarm, inspecting the POST via tcpdump or verbose mode to make sure it looks valid etc.10:43

sameerdougsz: how to check if its present in TSB ?11:30
sameer I am using influxdb db for staring metric logs11:30
sameer*TSDB11:30
dougszsameer: How are you viewing the metrics? With Grafana?11:30
dougszThat's one way.11:31
dougszAnother way - just run a query against InfluxDB11:31
sameeryes checking with query aainst influxdb11:31
sameerbut getting this error   " ERR: retention policy not found: "11:32

sameerall these retention policies11:34
dougszIt sounds like you have multitude or problems11:35
dougszs/or/of11:35
dougszI would suggest looking at an architecture diagram of Monasca, and starting from the Monasca API check that each component that you are using is working correctly.11:36
sameeryes i have checked that11:38
sameerall services are working11:38
sameerable to create metrics but its nt fetching from db11:38
sameermetric list is nt wrking , so can i guess its persister or influxdb issue ?11:40
dougszThat is where I would be looking. You can run a kafka console consumer to view metrics being written to kafka. If you see them there, then the next thing is, is the persister writing them to influxDB? and if it is, can you get them directly out of influxdb? And if that works, can you get them out of the monasca API?11:42
dougszI have seen the persister get 'jammed' on bad metrics before11:43
dougszIt's worth checking the logs carefully, in debug mode11:43
sameerwe hav to configre persister to store metrics in db ?11:45
dougszI don't know how you're deploying, but yes, the persister reads metrics from kafka and saves them in the time series database.11:45
sameertime series db is influxdb ri8 ?11:48
sameeryes you are right about persister11:48
sameeri want to know abt how persister saves metrics11:50
dougszsameer, check out the config file for monasca-persister12:04
sameerpersister-config.yaml is the only file we have to configure ri8 ?12:05
