Hi @mwreuter
I haven't looked in detail at SnapMirror stats largely because OnCommand Unified Manager (OCUM) does it already quite well with topology views, alerting, and xfer metrics. Also, since Graphite has no concept of relationships (except for the tree hierarchy) I'm not sure how best display src/dst metrics. I suppose I could aggregate things at the volume, or svm, or node level, but then I wonder if the value is gone. There are counter manager counters for snapmirror stuff, so assuming lagtime is in there you just have to decide how to structure your hierarchy and populating it is easy enough. If you can explain exactly what you want (like example metrics path/name) I can have a think about how easiest to achieve.
Anyway, back to OCUM, it's where I'd go for this request.
If you really want something in Graphite/Grafana you could also look at coding a small script that uses OnCommand API Services to get the data from OCUM and send it to Graphite. API Services offers a REST API with JSON responses making it pretty easy to get the data out of OCUM and into Graphite. I am co-presenting a session at Insight 2016 “Monitoring Performance Using NetApp OnCommand Performance Manager and API extensions” where we'll give an example of integrating with perf metrics. Out of curiousity I wanted to see how easy it is to get the metrics and it's pretty simple
This code:
import requests
requests.packages.urllib3.disable_warnings()
conf = {'url' : "https://10.64.29.23:8443/api/1.0", 'user' : 'admin', 'pass' : 'NetApp123'}
# Get SnapMirror lag times
resp_json = requests.get(conf['url'] + "/ontap/snap-mirrors", auth=(conf['user'], conf['pass']), verify=False).json()
for record in resp_json['result']['records']:
print "{} {} {}".format(record['source_location'], record['destination_location'], record['lag_time'])Results in this output:
[root@sdt-linux-infra4 insight]# python example-snapmirror.py
sdt-vs-nas1:vol_snapmirror_src sdt-vs-nas1:vol_snapmirror_dst 137
sdt-vs-inf1:NS_ns sdt-vs-inf1:NS_ns_mirror0001 138
sdt-vs-nas1:vol_snapmirror_src sdt-vs-nas1:vol_snapmirror_dst_vault 82325
We have <src> <dst> <lagtime>. So building a metrics path and sending to Graphite is a few more lines of code. Of course to get all metrics in, get summary metrics at various levels, make it generic and configurable, etc, is more work and why I haven't done it yet 🙂
