Sadly there is no documentation for this plugin.
#!/usr/bin/env python """ Plugin to monitor ArangoDB servers. It works with the new server statistics interface of ArangoDB 1.3. Not every value seems senseful, but there are nice graphs generated...

Usage: - Link or copy to /etc/munin/plugins - To enable extra graphs, also link to one or more of the possible links (given below) - Then restart munin-node Links possible: arangodb_conn HTTP client connections arangodb_time_total Total request/queue/connection time arangodb_bytes_total Total sent/received bytes Configuration: - No configuration required. Just enable the admin interface of ArangoDB. Thanks to the authors of other Python munin plugins. I've used some of them as inspiring example. Possible todos: - support of munin-like configuration parameters - add more statistics """ from os.path import basename import urllib2 import sys try: import json except ImportError: import simplejson as json def getServerStatus(group): raw = urllib2.urlopen( "http://127.0.0.1:8529/_admin/statistics" ).read() return json.loads( raw )[group] def doData(plugin_name): if plugin_name == 'arangodb_conn': print "connections.value " + str( getServerStatus('client')["httpConnections"] ) elif plugin_name== 'arangodb_time_total': data = getServerStatus('client') timeTotal = data['totalTime']['sum'] timeConnection = data['connectionTime']['sum'] timeRequest = data['requestTime']['sum'] timeQueue = data['queueTime']['sum'] print "total.value " + str(int(round(timeTotal))) print "connection.value " + str(int(round(timeConnection))) print "request.value " + str(int(round(timeRequest))) print "queue.value " + str(int(round(timeQueue))) elif plugin_name== 'arangodb_bytes_total': data = getServerStatus('client') bytesReceived = data['bytesReceived']['sum'] bytesSent = data['bytesSent']['sum'] print "received.value " + str(int(round(bytesReceived))) print "sent.value " + str(int(round(bytesSent))) else: pass def doConfig(plugin_name): if plugin_name == 'arangodb_conn': print "graph_title ArangoDB current connections" print "graph_args --base 1000 -l 0" print "graph_vlabel connections" print "graph_category db" print "connections.label connections" elif plugin_name == 'arangodb_time_total': print "graph_title ArangoDB total time" print "graph_args --base 1000 -l 0" print "graph_vlabel seconds" print "graph_category db" print "total.label total" print "connection.label connection" print "request.label request" print "queue.label queue" elif plugin_name == 'arangodb_bytes_total': print "graph_title ArangoDB total bytes" print "graph_args --base 1024" print "graph_vlabel total bytes received (-) / sent (+)" print "graph_category db" print "graph_order received sent" print "received.graph no" print "received.draw LINE2" print "received.type DERIVE" print "received.min 0" print "received.label Bytes received" print "received.cdef received,8,*" print "sent.draw LINE2" print "sent.type DERIVE" print "sent.min 0" print "sent.label bytes" print "sent.cdef sent,8,*" print "sent.negative received" else: pass plugin_name = basename(sys.argv) if __name__ == "__main__": if len(sys.argv) > 1 and sys.argv == "config": doConfig(plugin_name) else: doData(plugin_name)
