This blog explains how we configured and use Grafana to graph and visualize PDU data stored in InfluxDB.
Background InfluxDB is a time series database that we use to store dozens of metrics from all of our power distribution units (PDUs). This database is updated periodically with a python script that parses snmp data from our PDUs and stores it in the correct table and row. After getting the data into the db, we used Grafana to create graphs of some of the power consumption metrics so that we could easily see how much power was being used by each PDU.
Background VMware Affinity rules can solve many issues in a virtualized environment with out the need to create different clusters or datacenters to separate Virtual Machines. The specific need that we at Encore had for this was that when a vm is being cloned, if the VM was migrated to a different Host due to a vMotion, the custom spec with Kickstart files or Autounattended Syspreps would fail.
This was a random error that would only happened when vCenter or a host was overloaded.
Virtual Desktops are a topic that runs hot and cold through the enterprise space. Many enterprises begin pilots and projects in the space before building a clearly defined plan, and these are the environments that need additional remediation down the road. Before we start in with architecture, getting a firm answer to “Why do we need them?” is critical to a successfully scope, cost, and validate the design. This month we will focus on the security use case which is one of the ‘easy wins’ for virtual end user compute.
