NetApp is engineering simpler, more elegant tools for our
clients to manage their large technology deployments. We’ve found
recently that clients are relatively unaware of one tool that can make your
life much easier when you are investigating a performance issue: Performance
Archives.
Performance Archives has existed in ONTAP for a long
time, but beginning with 8.3 (released November 2014), the payload was updated
to specifically enable diagnostic use cases, trending use cases, etc. In
8.3, there is a command “system node autosupport
invoke-performance-archive” which allows customers (HTTPS enabled) to ship
back up to 6 hours worth of data at a time, collected a much higher resolution
than off-box PerfStat ever did (per-second for many counters) AND allows you
to “go back in time” up to 28 days, depending on customer
configuration.
The tool we
recommended pre-8.3, PerfStat, will continue to function through 8.4 per
current plan but we recognize it is post-failure collection
mechanism, which is not ideal. In other words, after you run into a
performance issue, you have to set up PerfStat to run and wait for that issue
to recur. Performance Archives gives you the ability to instantly look
back several hours and catch what the problem in the act.
We’re also making big improvements to Performance
AutoSupports: We are focused on efficiently streaming real-time
performance information to our cloud and making it easier to access this
content within the client-facing NetApp ASUP infrastructure. This will allow
for our customers and NetApp support engineers to do trending, analytics,
diagnostics and more.
And of course OnCommand Performance Manager remains
your go-to tool for retaining, graphing, and machine learning analysis for your
entire NetApp footprint.
