STOR2RRD has build-in alerting feature.
Alerting is based on reaching of performance thresholds.
You can define alarms for any storage and its volumes, pools or host.
Storage total (summary of all pools)
io: IO/sec total (read + write)
io read: IO/sec read
io write: IO/sec write
data: data throughput in MB/sec (read + write)
read: read data throughput
write: write data throughput
resp time: response time, latency
resp time read: response time read
resp time write: response time write
Note that some storage types do not support all metrics.
Emailing. You can place direct email address on each directive, use email groups or default email address.
Alert email has attached graph which shows utilization of the metric for past 25 hours.
Nagios support. You can configure Nagios to pick up alarms from STOR2RRD via standard NRPE module.
Nagios plug-in installation
External alerting via external shell script. Each alert can invoke defined script with given parameters.
You can use it for your integration needs.
SNMP trap: follow this to configure it
Alerting plug-ins to other monitoring tools can be developed on demand especially for customers under support contract
Limit: treshold level in IO per second, MB per seconds or mili seconds
Peak: The period of time in which avg traffic utilization has to be over the specified limit to generate an alert.
Repeat: Default time in minutes which says how often you should be alerted.
You can specify per storage/pool/volume different value in alert repeat time column of each alert
Exclude hours: time range in hours when alerts will be ignored
It is useful for exclusion of nightly batch jobs which usualy causing a big load.
Email group: you can create different email groups and direct alarms to them
All configuration is done through the UI item "Alerting Configuration"
Use your company's default email setup on the operating system you run STOR2RRD.
There is no any specific setup in the tool, it uses setting on the operating system.
In case of problems
Email setup on the Virtual Appliance
Email alert example 1
Alert when average write response time for storwize-home and pool01 is greater then 2.5 mili seconds during last 15 mins
STOR2RRD: POOL alert for storwize-home:pool01: response time write, actual value: 2.67 ms (limit 2.5)
Time: 18:24:00 18/06/2016
Metric: response time write
Average response time during last 15mins: 2.67 ms
Email alert example 2
Alert when average overall IO for storage storwize-home is greater then 50 IO/sec during last 5 mins
STOR2RRD: POOL-ALL: alert for storwize-home:all pools: io, actual value: 65 IO/sec (Limit 50)
Time: 19:48:00 18/06/2016
POOL-ALL: all pools
Average throughput during last 5mins: 65 IO/sec
