Description:

potsdb 1.0.3

potsdb======Python client to OpenTSDBThis was designed with a long running parent program in mind, where sending metrics was something that happens on the side.Implemented such that sending the metric "put" message to the Time Series Database API does not block the calling application. This is achieved by creating a background worker thread which takes metrics off the Queue, then sending them on a TCP socket to HOST. The client.log method simply sets up and puts the metric on the Queue, then returns.When the client object is instantiated, a temporary socket is created to the target HOST, PORT combination to check for connectivity. This may fail with a timeout error. However if the background thread encounters socket communication problems like timeout further down the line (in the sending metrics loop) then it will silently keep trying to reconnect forever.Keep in mind that if you send a bunch of metrics through .log then immediately quit, the background thread will also terminate, without having had enough time to send your metrics properly.Rate limiting for sending metrics over TCP is by default set to 100 Metrics Per Second. This can be overwritten upon instantiation.Installation===Clone this repo, then ```cd potsdbpython setup.py install```or```pip install potsdb```Usage===```import potsdb# minimum is hostname. port is defaulted to 4242:metrics = potsdb.Client('hostname.local')# all options:metrics = potsdb.Client('hostname.local', port=4242, qsize=1000, host_tag=True, mps=100, check_host=True)# qsize: Max Size of Queue. Note: if Queue reaches qsize, old metrics will be dropped. 0 = unlimited. Default is 100k# host_tag: True for automatic, string value for override, None for nothing# mps: Metrics Per Second rate limiting. Default is 0 (unlimited)# check_host: change to false to skip startup connectivity checking# Bare minimum is metric name, metric valuemetrics.send('test.metric2', 100)# tags can also be specifiedmetrics.send('test.metric5', 100, extratag1='tagvalue', extratag2='tagvalue')# host tag is set automatically, but can be overwrittenmetrics.send('test.metric6', 34, host='app1.local')# waits for all outstanding metrics to be sent and background thread closesmetrics.wait()```Contributers===Potsdb was created by OrionVM as an internal project which was subsequently open sourced.
