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 […]
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 […]
