Monitor Service Function Instance Surrogate (VMs)

Common context: Usage and Performance

All of the specific context measurements below carry the following common context (this has not be replicated for brevity) for both usage and performance measurements. In this example, we illustrate using 2 surrogate VMs.

| measurement | tag | tag | tag | tag | tag | | --- | --- | --- | --- | --- | --- | --- | | <measurement>, | location="DC1", | sfc="Scenario1_Template", | sfc_i="Scenario1_Template_I1", | sf_package="MS_STREAMING", | sf_i="MS_STREAMING_1", | vm_instance ="MPEG_DASH_Server1" | | <measurement>, | location="DC2", | sfc="Scenario1_Template", | sfc_i="Scenario1_Template_I1", | sf_package="MS_STREAMING", | sf_i="MS_STREAMING_2", | vm_instance ="MPEG_DASH_Server2" |

Also NOTE: the metrics provided in the measurements below are effectively a 'snapshot' of usage over a relatively small period of time. The length of this snapshot may vary, depending on the underlying implementation of the instrumentation, so we might have to assume this snapshot is close to 'instant'.

USAGE: Monitor Service Function Instance Surrogate (VMs)

Specific context: CPU usage

measurement <common tags> field field timestamp
vm_host_cpu_usage <common tags> cpu_usage=40, cpu_usage_system=5 1515583926868000000
Specific context: RAM usage

Specific context: storage usage

Specific context: network usage

Not sure about this one. For example: Bytes over port_M - is this a total byte count that increments over time or is it a snapshot shot of throughput on port M over the course of, say, 1 second?

| measurement | <common tags> | field | field | timestamp | | --- | --- | --- | --- | --- | --- | | vm_host_network_usage | <common tags> | rx_bytes_port_M=5242880, | tx_bytes_port_M=15728640 | 1515583926868000000 |
