DATABASE COMMANDS

MongoDB

pmm-admin add mongodb [FLAGS] [node-name] [node-address]

Add MongoDB to monitoring.

FLAGS:

--node-id=node-id
Node ID (default is auto-detected).
--pmm-agent-id=pmm-agent-id
The pmm-agent identifier which runs this instance (default is auto-detected).
--username=username
MongoDB username.
--password=password
MongoDB password.
--agent-password=password

Override the default password for accessing the /metrics endpoint. (Username is pmm and default password is the agent ID.)

Avoid using special characters like ‘', ‘;’ and ‘$’ in the custom password.

--query-source=profiler
Source of queries, one of: profiler, none (default: profiler).
--environment=environment
Environment name.
--cluster=cluster
Cluster name.
--replication-set=replication-set
Replication set name.
--custom-labels=custom-labels
Custom user-assigned labels.
--skip-connection-check
Skip connection check.
--tls
Use TLS to connect to the database.
--tls-skip-verify
Skip TLS certificates validation.
--tls-certificate-key-file=PATHTOCERT
Path to TLS certificate file.
--tls-certificate-key-file-password=IFPASSWORDTOCERTISSET
Password for TLS certificate file.
--tls-ca-file=PATHTOCACERT
Path to certificate authority file.
--metrics-mode=mode
Metrics flow mode for agents node-exporter. Allowed values: - auto: chosen by server (default). - push: agent will push metrics. - pull: server scrapes metrics from agent.
--max-query-length=NUMBER (This parameter is available starting with PMM 2.32.0.)

Limit query length in QAN. Allowed values: - -1: No limit. - 0: Default value. The default value is 2048 chars. - >0: Query will be truncated after chars.

Ensure you do not set the value of max-query-length to 1, 2, or 3. Otherwise, the PMM agent will get terminated.

Advanced Options

PMM starts the MongoDB exporter by default only with diagnosticdata and replicasetstatus collectors enabled.

FLAGS:

--enable-all-collectors
Enable all collectors.
--disable-collectors
Comma-separated list of collector names to exclude from exporter.
--max-collections-limit=-1

Disable collstats, dbstats, topmetrics and indexstats if there are more than collections. 0: No limit. Default is -1, PMM automatically sets this value.

A very high limit of max-collections-limit could impact the CPU and Memory usage. Check --stats-collections to limit the scope of collections and DB’s metrics to be fetched.

--stats-collections=db1,db2.col1
Collections for collstats & indexstats.
Enable all collectors

To enable all collectors, pass the parameter --enable-all-collectors in the pmm-admin add mongodb command. This will enable collstats, dbstats, indexstats, and topmetrics collectors.

Disable some collectors

To enable only some collectors, pass the parameter --enable-all-collectors along with the parameter --disable-collectors.

For example, if you want all collectors except topmetrics, specify:

--enable-all-collectors --disable-collectors=topmetrics
Limit dbStats, collStats and indexStats

By default, PMM decides the limit for the number of collections to monitor the collStats and indexStats collectors.

You can also set an additional limit for the collStats, indexStats, dbStats, and topmetrics collectors with the --max-collections-limit parameter.

Set the value of the parameter --max-collections-limit to:

  • 0: which indicates that collStats and indexStats can handle unlimited collections.
  • n, which indicates that collStats and indexStats can handle <=n collections. If the limit is crossed - exporter stops collecting monitoring data for the collStats and indexStats collectors.
  • -1 (default) doesn’t need to be explicitly set. It indicates that PMM decides how many collections it would monitor, currently <=200 (subject to change).

To further limit collections to monitor, enable collStats and indexStats for some databases or collections:

  • Specify the databases and collections that collStats and indexStats will use to collect data using the parameter --stats-collections. This parameter receives a comma-separated list of name spaces in the form database[.collection].
Examples

To add MongoDB with all collectors (diagnosticdata, replicasetstatus, collstats, dbstats, indexstats, and topmetrics) with default limit detected by PMM (currently <=200 collections, but subject to change):

pmm-admin add mongodb --username=admin --password=admin_pass --enable-all-collectors mongodb_srv_1 127.0.0.1:27017

To add MongoDB with all collectors (diagnosticdata, replicasetstatus, collstats, dbstats, indexstats, and topmetrics) with max-collections-limit set to 1000:

pmm-admin add mongodb --username=admin --password=admin_pass --enable-all-collectors --max-collections-limit=1000 mongodb_srv_1 127.0.0.1:27017

To enable all the collectors with an unlimited number of collections monitored:

pmm-admin add mongodb --username=admin --password=admin_pass --enable-all-collectors --max-collections-limit=0 mongodb_srv_1 127.0.0.1:27017

To add MongoDB with default collectors (diagnosticdata and replicasetstatus):

pmm-admin add mongodb --username=admin --password=admin_pass mongodb_srv_1 127.0.0.1:27017

Disable collstats collector and enable all the others without limiting max-collections-limit:

pmm-admin add mongodb --username=admin --password=admin_pass --enable-all-collectors --max-collections-limit=0 --disable-collectors=collstats mongodb_srv_1 127.0.0.1:27017

If --stats-collections=db1,db2.col1 then the collectors are run as follows:

Database Collector is run on
db1 All the collections
db2 Only for collection col1

Enable all collectors and limit monitoring for dbstats, indexstats, collstats and topmetrics for all collections in db1 and col1 collection in db2, without limiting max-collections-limit for a number of collections in db1:

pmm-admin add mongodb --username=admin --password=admin_pass --enable-all-collectors --max-collections-limit=0 --stats-collections=db1,db2.col1 mongodb_srv_1 127.0.0.1:27017

Resolutions

PMM collects metrics in two resolutions to decrease CPU and Memory usage: high and low resolutions.

In high resolution we collect metrics from collectors which work fast: - diagnosticdata - replicasetstatus - topmetrics

In low resolution we collect metrics from collectors which could take some time: - dbstats - indexstats - collstats

MySQL

pmm-admin add mysql [FLAGS] node-name node-address | [--name=service-name] --address=address[:port] | --socket

Add MySQL to monitoring.

FLAGS:

--address

Avoid using special characters like ‘', ‘;’ and ‘$’ in the custom password.

--query-source=slowlog
Source of SQL queries, one of: slowlog, perfschema, none (default: slowlog). For slowlog query source, you need change permissions for specific files. Root permissions are needed for this.
--size-slow-logs=N

Rotate slow log file at this size. If 0, use server-defined default. Negative values disable log rotation. A unit suffix must be appended to the number and can be one of:

  • KiB, MiB, GiB, TiB for base 2 units (1024, 1048576, etc).
--disable-queryexamples
Disable collection of query examples.
--disable-tablestats

Disable table statistics collection.
