# Metrics structure used to register the metrics and also translate/interpret the incoming metrics.

|
||||
The Metrics table is used to register metrics and translate/interpret the incoming metrics.
|
||||
|
||||
This table describes all of the prometheus metrics that are recognised by the application.
|
||||
The background documentation for defining metrics is at: https://prometheus.io/docs/introduction/
|
||||
In particular, the naming practices should be adhered to: https://prometheus.io/docs/practices/naming/
|
||||
The Ruby Client docs are also useful: https://github.com/prometheus/client_ruby
|
||||
|
||||
The table here allows the currently used stats definitions to be translated correctly for Prometheus.
|
||||
The current format is of the form A.B.C, where the final fields may be actual values (e.g. poolname).
|
||||
Prometheus metrics cannot use the '.' as a character, so this is either translated into '_' or
|
||||
variable parameters are expressed as labels accompanying the metric.
|
||||
|
||||
Sample statistics are:
|
||||
# Example showing hostnames (FQDN)
|
||||
migrate_from.pix-jj26-chassis1-2.ops.puppetlabs.net
|
||||
migrate_to.pix-jj26-chassis1-8.ops.puppetlabs.net
|
||||
|
||||
# Example showing poolname as a parameter
|
||||
poolreset.invalid.centos-8-x86_64
|
||||
|
||||
# Examples showing similar sub-typed checkout stats
|
||||
checkout.empty.centos-8-x86_64
|
||||
checkout.invalid.centos-8-x86_64
|
||||
checkout.invalid.unknown
|
||||
checkout.success.centos-8-x86_64
|
||||
|
||||
# Stats without any final parameter.
|
||||
connect.fail
|
||||
connect.open
|
||||
delete.failed
|
||||
delete.success
|
||||
|
||||
# Stats with multiple param_labels
|
||||
vmpooler_user.debian-8-x86_64-pixa4.john
|
||||
|
||||
The metrics implementation here preserves the existing framework which will continue to support
|
||||
graphite and statsd (since vmpooler is used outside of puppet). Some rationalisation and renaming
|
||||
of the actual metrics was done to get a more usable model to fit within the prometheus framework.
|
||||
This particularly applies to the user stats collected once individual machines are terminated as
|
||||
this would have challenged prometheus' ability due to multiple (8) parameters being collected
|
||||
in a single measure (which has a very high cardinality).
|
||||
|
||||
Prometheus requires all metrics to be pre-registered (which is the primary reason for this
|
||||
table) and also uses labels to differentiate the characteristics of the measurement. This
|
||||
is used throughout to capture information such as poolnames. So for example, this is a sample
|
||||
of the prometheus metrics generated for the "vmpooler_ready" measurement:
|
||||
|
||||
# TYPE vmpooler_ready gauge
|
||||
# HELP vmpooler_ready vmpooler number of machines in ready State
|
||||
vmpooler_ready{vmpooler_instance="vmpooler",poolname="win-10-ent-x86_64-pixa4"} 2.0
|
||||
vmpooler_ready{vmpooler_instance="vmpooler",poolname="debian-8-x86_64-pixa4"} 2.0
|
||||
vmpooler_ready{vmpooler_instance="vmpooler",poolname="centos-8-x86_64-pixa4"} 2.0
|
||||
|
||||
Prometheus supports the following metric types:
|
||||
(see https://prometheus.io/docs/concepts/metric_types/)
|
||||
|
||||
Counter (increment):
|
||||
A counter is a cumulative metric that represents a single monotonically increasing counter whose
|
||||
value can only increase or be reset to zero on restart
|
||||
|
||||
Gauge:
|
||||
A gauge is a metric that represents a single numerical value that can arbitrarily go up and down.
|
||||
|
||||
Histogram:
|
||||
A histogram samples observations (usually things like request durations or response sizes) and
|
||||
counts them in configurable buckets. It also provides a sum of all observed values.
|
||||
This replaces the timer metric supported by statsd
|
||||
|
||||
Summary :
|
||||
Summary provides a total count of observations and a sum of all observed values, it calculates
|
||||
configurable quantiles over a sliding time window.
|
||||
(Summary is not used in vmpooler)
|
||||
|
||||
vmpooler_metrics_table is a table of hashes, where the hash key represents the first part of the
|
||||
metric name, e.g. for the metric 'delete.*' (see above) the key would be 'delete:'. "Sub-metrics",
|
||||
are supported, again for the 'delete.*' example, this can be subbed into '.failed' and '.success'
|
||||
|
||||
The entries within the hash as are follows:
|
||||
|
||||
mtype:
|
||||
Metric type, which is one of the following constants:
|
||||
M_COUNTER = 1
|
||||
M_GAUGE = 2
|
||||
M_SUMMARY = 3
|
||||
M_HISTOGRAM = 4
|
||||
|
||||
torun:
|
||||
Indicates which process the metric is for - within vmpooler this is either ':api' or ':manager'
|
||||
(there is a suggestion that we change this to two separate tables).
|
||||
|
||||
docstring:
|
||||
Documentation string for the metric - this is displayed as HELP text by the endpoint.
|
||||
|
||||
metric_suffixes:
|
||||
Array of sub-metrics of the form 'sub-metric: "doc-string for sub-metric"'. This supports
|
||||
the generation of individual sub-metrics for all elements in the array.
|
||||
|
||||
param_labels:
|
||||
This is an optional array of symbols for the final labels in a metric. It should not be
|
||||
specified if there are no additional parameters.
|
||||
|
||||
If it specified, it can either be a single symbol, or two or more symbols. The treatment
|
||||
differs if there is only one symbol given as all of the remainder of the metric string
|
||||
supplied is collected into a label with the symbol name. This allows the handling of
|
||||
node names (FQDN).
|
||||
|
||||
To illustrate:
|
||||
1. In the 'connect.*' or 'delete.*' example above, it should not be specified.
|
||||
2. For the 'migrate_from.*' example above, the remainder of the measure is collected
|
||||
as the 'host_name' label.
|
||||
3. For the 'vmpooler_user' example above, the first parameter is treated as the pool
|
||||
name, and the second as the username.
