PMM Settings Page

The PMM Settings page lets you configure a number of PMM options.

Note

Press Apply changes to store any changes.

Metrics resolution

Metrics are collected at three intervals representing low, medium and high resolutions. Short time intervals are regarded as high resolution metrics, while those at longer time intervals are low resolution.

../_images/PMM_Settings_Metrics_Resolution.jpg

The Metrics Resolution radio button lets you select one of four presets.

  • Rare, Standard and Frequent are fixed presets.
  • Custom is an editable preset.

Each preset is a group of Low, Medium and High metrics resolution values. Low resolution intervals increases the time between collection, resulting in low-resolution metrics and lower disk usage. High resolution intervals decreases the time between collection, resulting in high-resolution metrics and higher disk usage.

The default values for the fixed presets are:

Rare

  • Low: 300 seconds
  • Medium: 180 seconds
  • High: 60 seconds

Standard

  • Low: 60 seconds
  • Medium: 10 seconds
  • High: 5 seconds

Frequent

  • Low: 30 seconds
  • Medium: 5 seconds
  • High: 1 second

Values for the Custom preset can be entered as values, or changed with the arrows.

Note

If there is poor network connectivity between PMM Server and PMM Client, or between PMM Client and the database server it is monitoring, scraping every second may not be possible when the network latency is greater than 1 second.

Data Retention

Data retention specifies how long data is stored by PMM Server.

Telemetry

The Telemetry switch enables gathering and sending basic anonymous data to Percona, which helps us to determine where to focus the development and what is the uptake of the various versions of PMM. Specifically, gathering this information helps determine if we need to release patches to legacy versions beyond support, determining when supporting a particular version is no longer necessary, and even understanding how the frequency of release encourages or deters adoption.

Currently, only the following information is gathered:

  • PMM Version,
  • Installation Method (Docker, AMI, OVF),
  • the Server Uptime.

We do not gather anything that would make the system identifiable, but the following two things are to be mentioned:

  1. The Country Code is evaluated from the submitting IP address before it is discarded.
  2. We do create an “instance ID” - a random string generated using UUID v4. This instance ID is generated to distinguish new instances from existing ones, for figuring out instance upgrades.

The first telemetry reporting of a new PMM Server instance is delayed by 24 hours to allow sufficient time to disable the service for those that do not wish to share any information.

There is a landing page for this service, available at check.percona.com, which clearly explains what this service is, what it’s collecting, and how you can turn it off.

Grafana’s anonymous usage statistics is not managed by PMM. To activate it, you must change the PMM Server container configuration after each update.

As well as via the PMM Settings page, you can also disable telemetry with the -e DISABLE_TELEMETRY=1 option in your docker run statement for the PMM Server.

Note

  1. If the Security Threat Tool is enabled in PMM Settings, Telemetry is automatically enabled.
  2. Telemetry is sent immediately; the 24-hour grace period is not honored.

Check for updates

When active, PMM will automatically check for updates and put a notification in the Updates dashboard if any are available.

Security Threat Tool

The Security Threat Tool performs a range of security-related checks on a registered instance and reports the findings.

It is disabled by default.

It can be enabled in PMM > PMM Settings > Settings > Advanced Settings > Security Threat Tool.

The checks take 24 hours to complete.

The results can be viewed in PMM > PMM Database Checks.

SSH Key Details

This section lets you upload your public SSH key to access the PMM Server via SSH (for example, when accessing PMM Server as a virtual appliance).

../_images/PMM_Settings_SSH_Key.jpg

Enter your public key in the SSH Key field and click Apply SSH Key.

Alertmanager integration

The Prometheus Alertmanager manages alerts from Prometheus, deduplicating, grouping, and routing them to the appropriate receiver or display component.

This section lets you configure integration of Prometheus with an external Alertmanager.

  • The Alertmanager URL field should contain the URL of the Alertmanager which would serve your PMM alerts.
  • The Prometheus Alerting rules field is used to specify alerting rules in the YAML configuration format.
../_images/PMM_Settings_Alertmanager_Integration.jpg

Fill both fields and click the Apply Alertmanager settings button to proceed.

Percona Platform

This panel is where you create, and log into and out of your Percona Platform account.

Logging in

../_images/PMM_Settings_Percona_Platform.jpg

If you have a Percona Platform account, enter your credentials and click Login.

Logging out

../_images/PMM_Settings_Sign_Out.jpg

Click Sign out to log out of your Percona Platform account.

Create an account

../_images/PMM_Settings_Sign_Up.jpg

To create a Percona Platform account:

  • Click Sign up
  • Enter a valid email address in the Email field
  • Choose and enter a strong password in the Password field
  • Select the check box acknowledging our terms of service and privacy policy
  • Click Sign up

A brief message will confirm the creation of your new account and you may now log in with these credentials.

Note

Your Percona Platform account is separate from your PMM User account.

Diagnostics

PMM can generate a set of diagnostics data which can be examined and/or shared with Percona Support in case of some issue to solve it faster. You can get collected logs from PMM Server by clicking the Download server diagnostics button.
