pganalyze Collector settings
The collector can be configured either through an
INI config file (in a package-based install) or environment
variables (typically for running via its Docker image). Most settings can be configured through either mechanism.
If both are present, the config file takes precedence. Note that a single collector instance can monitor more than
one database server, though this is not supported when configuring through environment variables.
INI-based setup, the
[pganalyze] section describes settings that apply to all servers. Other sections
describe the servers to monitor, how to connect to them, and server-specific configuration settings. You should
name the other sections after the servers they correspond to, though note these are not the names that will appear
in the app. In-app names are based on hostname settings as determined during monitoring. When you set environment
variables in addition to specifying a configuration file, the environment variable settings apply to all monitored
After you make changes, you can run
pganalyze-collector --test --reload to verify the new configuration and load
the new configuration in the collector background process if they work correctly. This minimizes monitoring
interruptions and simplifies config file updates.
The tables below list configuration settings, their defaults if not set, and their descriptions. If a setting is
configurable through environment variables, the environment variable name follows the setting in parentheses.
Environment variables for boolean settings expect
1 for true and
0 for false.
Note that these settings apply to the latest version of the collector.
Common settings for configuring collector behavior, independent of the platform.
|api_key (||n/a, required||API key to authenticate the collector to the pganalyze app. We will show this when adding a server in the app, and you can review it on your organization's Settings page under the API keys tab.|
|api_base_url (||https://api.pganalyze.com||Base URL for contacting the pganalyze API. You typically do not need to change this, unless you are running pganalyze Enterprise Edition.|
|skip_if_replica (||false||Skip all metadata collection and snapshot submission while this server is a replica (according to |
|enable_log_explain (||false||Enable log-based EXPLAIN. See setup instructions, but note we recommend using auto_explain instead if possible.|
How to connect to the server(s) pganalyze will be monitoring. Note that when monitoring multiple databases on the same server, the first specified is considered the primary database. This is where helper functions are expected to be defined, and the one we connect to for server-wide metrics.
|db_url (||n/a, either this or individual settings below are required||URL of the database server to monitor|
|db_name (||n/a, either this or db_url is required||Name of database to monitor; or, comma-separated list of all databases to monitor, starting with primary (last entry can be |
|db_username (||n/a, either this or db_url is required||Postgres user to connect as (we recommend using the pganalyze monitoring user here)|
|db_password (||[none]||Password for the Postgres user|
|db_host (||n/a, either this or db_url is required||Host to connect to|
|db_port (||5432||Port to connect on|
|db_sslmode (||prefer||The |
|db_sslrootcert (||system certificate store||Path to SSL certificate authority (CA) certificate(s) to use to verify the server's certificate, or one of |
|db_sslrootcert_contents (||n/a, see above||Alternative to above, using actual contents of the certificate(s) instead|
|db_sslcert (||[none]||Path to the client SSL certificate (optional, usually not required)|
|db_sslcert_contents (||[none]||Alternative to above, using actual contents of the certificate instead|
|db_sslkey (||[none]||Path to the secret key used for the client certificate|
|db_sslkey_contents (||[none]||Alternative to above, using actual contents of the key|
We take the responsibility of access to your database very seriously. As discussed above, we already limit the direct access we have to your data, but some personally-identifiable information or other sensitive values can still come up in query text or logs. To address this, the collector has several settings to filter these before we collect them.
|filter_log_secret (||none||One or more of |
|filter_query_sample (||none||Either |
|filter_query_text (||unparsable||Either |
Our recommended configuration for servers containing highly sensitive data is as follows:
filter_log_secret: all filter_query_sample: all filter_query_text: unparsable
Note that this automatically turns off the query sample and EXPLAIN plan features, as they may contain sensitive data in the query text. We are working to provide more fine-grained PII filtering options in the future, including the option to sanitize EXPLAIN plans automatically.
The pganalyze collector limits the number of schema objects (tables, views, etc.) that can be monitored on each database server. This limit is currently 5,000 tables or views per database server. If this limit is exceeded, no schema information will be collected.
You can avoid reaching this limit by using the following setting to select which tables/views should be excluded:
|ignore_schema_regexp (||[none]||Skip collecting metadata for all matching tables, schemas, or functions; match is checked against schema-qualified object names (e.g. to ignore table "foo" only in the public schema, set to |
To validate whether the setting is working as intended, you can run a query on your database server to count the number of monitored tables and views. Note you would have to run this on each database on the server and then summarize the counts, which should not exceed the 5,000 limit in aggregate:
SELECT current_database() AS dbname, COUNT(*) AS table_and_view_count FROM pg_class c LEFT JOIN pg_catalog.pg_namespace n ON (n.oid = c.relnamespace) WHERE c.relkind IN ('r','v','m','p') AND c.relpersistence <> 't' AND c.relname NOT IN ('pg_stat_statements') AND n.nspname NOT IN ('pg_catalog','pg_toast','information_schema') AND (n.nspname || '.' || c.relname) !~* 'REGEXP';
Make sure to replace
REGEXP with the value of your
