vSphere collects a lot of performance metrics data on a VMware cluster. Our problem was that we cannot find a complete documentation on what are all those performance metrics data collected and what are the units of the collected metric data. We have asked VMware professional services engineer about this and his response was that VMware does not have the metrics data documented.
However, in Chapter 16 of the vSphere Web Services Programming Guide, it talked about the fact that you can retrieve the metrics catalog from vSphere itself. Although this document talks about retrieving the metrics catalog via vSphere Web Services SDK, you can also retrieve the metrics catalog with PowerCLI. Below is a F# script that retrieves vSphere metrics catalog:
#r @"C:\pkg\VMware\Infrastructure\vSphere PowerCLI\VMware.Vim.dll"
open System
open VMware.Vim
open System.Collections.Specialized
let client = new VimClient()
let service = client.Connect(serviceUrl)
// Must login to do anything - if you are getting null values, it means the session automatically timed out
client.Login(userId,password)
let printMetricCatalog () =
// counterId max is arbitrarily set, I tried other values
// and still produced the same number of returned metrics
let counterIds = seq {1 .. 1000}
let perfMgr = new PerformanceManager(client,client.ServiceContent.PerfManager)
let metrics = perfMgr.QueryPerfCounter(counterIds |> Seq.toArray)
let dumpAllMetricData (metric:PerfCounterInfo) =
printfn "-------------------------------------------------------------------\n"
printfn "Key : %i" metric.Key
printfn "Level : %A" metric.Level
printfn "PerDeviceLevel : %A" metric.PerDeviceLevel
printfn "RollupType : %A" metric.RollupType
printfn "StatsType : %A" metric.StatsType
printfn "Group.Label : %s" metric.GroupInfo.Label
printfn "Group.Key : %s" metric.GroupInfo.Key
printfn "Group.Summary : %s" metric.GroupInfo.Summary
printfn "NameInfo.Label : %s" metric.NameInfo.Label
printfn "NameInfo.Key : %s" metric.NameInfo.Key
printfn "NameInfo.Summary: %s" metric.NameInfo.Summary
printfn "UnitInfo.Label : %s" metric.UnitInfo.Label
printfn "UnitInfo.Key : %s" metric.UnitInfo.Key
printfn "UnitInfo.Summary: %s" metric.UnitInfo.Summary
let dumpMetricData (metric:PerfCounterInfo) = printfn "\t%s (%s) - %A stat, rollup: %A"
(metric.NameInfo.Label)
(metric.UnitInfo.Label)
(metric.StatsType)
(metric.RollupType)
// Break metrics catalog by metric groups
let metricGroups = metrics |> Seq.map (fun metric -> metric.GroupInfo.Label) |> Set.ofSeq |> Set.toSeq
// Dump short version of metrics catalog
metricGroups
|> Seq.iter (fun group -> printfn "\n--------------------------------------------------"
printfn " Metric Group : %s" group
printfn "--------------------------------------------------"
metrics
|> Seq.filter (fun metric -> metric.GroupInfo.Label = group)
|> Seq.iter dumpMetricData)
// Dump complete version of metrics catalog
metrics |> Seq.iter dumpAllMetricData
printMetricCatalog()
Here's a dump of the metrics catalog reformatted to display as HTML tables:
