Meter - Built-In Server Metrics

The TrueSight Pulse Meter collects the following baseline (core) 8 server metrics and 12 extended server metrics, which can be shown using Dashboards. The core metrics are:


MetricDescription (units)
CPU Utilization Overall CPU utilization (%)
Memory Usage Overall memory utilization (%)
Disk Writes Number of disk write operations
Disk Reads Number of disk read operations
Network In Network traffic received on all interfaces (Bytes)
Network Out Network traffic sent on all interfaces sent (Bytes)
Disk Bytes Written Number of bytes written to all disks (Bytes)
Disk Bytes Read Number of bytes read from all disks (Bytes)


The 12 extended server metrics, which are only available to standard plan and advanced plan (non-free) customers are: 

MetricDescription (units)
CPU IO Wait Time The percentage of CPU time spent waiting for IO operations (%)
CPU System Time The percentage of available CPU time being utilized by the OS (%)
CPU User Time

The percentage of available CPU time being utilized by programs (%)

CPU Stolen Time The percentage of time a virtual machine was ready to run but was not allowed to run by the host OS (%)
One Minute Load Average An averaging of the number of processes utilizing or waiting for CPU time over that last minute
Filesystem Utilization Percentage of disk space used (written on). This is the total among all non-virtual, local filesystems (%)
Memory Bytes Free The amount of unused memory by programs and the OS (bytes)
Processor Queue The number of processes that are waiting to run on a CPU
Context Switches The number of switches between programs and the OS in the last second.
Total Number of Processes The number of processes running, including duplicates. Processes are programs that support applications.
Number of Idle Processes The number of processes that have not executed for more than 20 seconds.
Number of Threads Number of process threads running. A single process can have many threads, but a thread can only have one process.


There are two more "reserved" metrics (App. Req. Count and App. Resp. Time) used when instrumenting your application using one of provided TrueSight Pulse SDKs (not plug-ins). Those are deprecated and will disappear in near future. You can use plug-ins, which would collect additional metrics and or send custom metrics through API. 

App. Req. Count Total count of application requests, can drill down for details
App. Resp. Time Total application response time (msec), can drill down for details
