Monitoring

Listing of Monitoring metrics

Computing node metrics

Name	Description	Source	Type (unit)
cpu{idle, system, user, nice}	Amount of time spent by the CPU in various states, most notably executing user code, executing system code, waiting for IO-operations and being idle	collectd	double (%)
systemLoad{avg1, avg5, avg15}	The system load is defined as the number of runnable tasks in the run-queue and is provided as a one, five or fifteen minute average	collectd	double
memory{free, used, cached, buffered}	Physical memory utilization	collectd	double (B)
diskThroughput{read, write}	Dish throughput	collectd	double (Bps)
diskIO{read, write}	Disk operations per second	collectd	double (iops)
network{incommingData, outgoingData, incommingPackets, outgoingPackets}	Network incoming and outgoing throughput, incoming outgoing number of packets per second	collectd	double (Bps, pps)

Process metrics

Name	Description	Type (unit)
pcpu	CPU utilization of the process in "##.#" format. Currently, it is the CPU time used divided by the time the process has been running (cputime/realtime ratio), expressed as a percentage (it will not add up to 100%).	double (%)
pmem	Ratio of the process's resident set size to the physical memory on the machine.	double (%)
etime	Elapsed time since the process was started, in the form.	string ([[DD-]hh:]mm:ss)

Network node metrics

Name	Description	Type (unit)
networkThroughput{if0, if1, …}	Network throughput per interface	double (b/s)
droppedPackets	Dropped packets in the device	unsigned int

O² Specific metrics

Name	Description	Entity	Type (unit)
timeFrameRate	How many Time Frames per second are generated	EPN	double (Hz)
timeFrameIncomplete	Number of incomplete Time Frames	EPN	unsigned int
fiberLinkState	Sate of fiber link (enabled/disabled)	FLP	bool (ON/OFF)
fiberLinkBackpressure	Occupancy of fiber link	FLP	double (%)
storageOccupancy	Disks occupancy of storage facility	Storage	double (%)
storageThroughput	Throughput to storage facility	Storage	double (bps)
