Overview This post will cover some slides from my presentation of the same name which I have presented at a few conferences. I have omitted the tooling setup and graphics of issues as this just shows impact not the reasoning behind it. Traditional bottleneck In the above slide we can see that the time to […]
Hi as I have had a lot of traffic for the 3PAR performance I have added a short video below on how to import and use the overall Array Performance views.
Hi as I have had a lot of traffic for the 3PAR performance I have added two videos below on how to setup the host and array views which covers hosts and volumes. When looking at the performance data for the volumes you may notice that these are spiking in nature this is down to […]
Overview In this post we will take a look at Ports the data is gathered by the statport command. We can view different metrics when parsing the data from this command including iops, throughput, latency and queuing. Cache statcmp Cpu statcpu Hosts statvlun / statvlun -hostsum / -vvsum Ports statport -host Volumes statvlun -vvsum Getting […]
Overview In this post we will take a look a Hosts and Volumes the same metrics are available for both so to save duplication of effort and two posts this will be combined. We can gather details on hosts and volumes using the standard statvlun command and we can also pass in a few options […]
Overview In the previous post we covered Cache and will now look at monitoring the cpu performance of the 3PAR Array. Metrics are gathered using the statcpu command. Cache statcmp Cpu statcpu Hosts statvlun / statvlun -hostsum Ports statport -host Volumes statvlun -vvsum Getting started.. How do I run the statcpu command? Below shows how […]
Overview This series of posts will look at HPE 3PAR performance monitoring using the main stat commands for realtime analysis and culminate in a similar Grafana/Influxdb solution to look at historical statistics. I will be covering the following key areas: Cache statcmp Cpu statcpu Hosts statvlun / statvlun -hostsum Ports statport -host Volumes statvlun -vvsum I will […]
Overview This post aims to cover overall array stats. We will create one dashboard to show the overall array stats and then we will break this down into a secondary dashboard focusing on individual array ports and how we need these to identify workloads driving IOPS and BW, this view will also help identify if […]
Overview When I started writing this blog I realised that I had more than one parsing script based on the statistics I was looking to gather and as such I have now merged these into four wrapper scripts and single perl script. This post is really a copy of Hosts but for Volumes with new […]
Overview In the first blog in this series we added in IOPS and explained how we could look to add in Bandwidth and Latency. In this post we will cover off creating the whole view and adding in the next post we will cover adding in volumes and server host bus adapter details. Bringing it […]
