SiriDB can start with environment variables and/or with a configuration file. By default SiriDB will search for the configuration file in /etc/siridb/siridb.conf but alternatively you can specify a custom path by using the -c/--config argument.

$ siridb-server -c /my/path/siridb.conf

An example configuration file can be found here:

However be aware that the environment variables will overwrite the configuration file settings if both apply to the same setting.

Environmental variables:

Variable Default Description
SIRIDB_SERVER_NAME %HOSTNAME:9010 SiriDB will use this address:port for it’s back-end connections. This must be an address that other servers can use to connect to. For example IPv4, IPv6 or a fqdn are all possible. When using IPv6 be sure to wrap the ip address with square brackets. For example [::1]:9010. The default value is %HOSTNAME:9010. The variable %HOSTNAME will be translate to the systems host name.
SIRIDB_BIND_SERVER_ADDRESS Listen for SiriDB-server connections only on localhost. Use value (or :: for IPv6) to bind to all interfaces.
SIRIDB_LISTEN_CLIENT_PORT 9000 SiriDB will listen for client connections on this port number.
SIRIDB_BIND_CLIENT_ADDRESS Listen for client connections only on localhost. Use value (or :: for IPv6) to bind to all interfaces.
SIRIDB_IP_SUPPORT ALL When ip_support is set to ALL, SiriDB will listen and connect to both IPv4 and IPv6 addresses. Valid options are ALL, IPV4ONLY and IPV6ONLY.
SIRIDB_DEFAULT_DB_PATH /var/lib/siridb SiriDB will load databases from, and create databases in this location.
SIRIDB_OPTIMIZING_INTERVAL 3600 SiriDB will run an optimize task each X seconds. A value of 0 (zero) disables optimizing.
SIRIDB_HEARTBEAT_INTERVAL 30 SiriDB uses a heart-beat interval to keep connections with other servers online.
SIRIDB_BUFFER_SYNC_INTERVAL 0 SiriDB can run fsync on the buffer file on an interval in milliseconds. This value is set to 0 by default which tells SiriDB to run fsync after each insert request. When having many insert requests per second, it can be useful to use an interval like 500 milliseconds.
SIRIDB_MAX_OPEN_FILES 32768 SiriDB will not open more shard files than max_open_files. Note that the total number of open files can be sligtly higher since SiriDB also needs a few other files to write to.
SIRIDB_ENABLE_SHARD_COMPRESSION 1 Use shard compression for storing data points. Set value 0 to disable shard compression.
SIRIDB_ENABLE_PIPE_SUPPORT 0 Enable named pipe support for client connections.
SIRIDB_PIPE_CLIENT_NAME siridb_client.sock SiriDB will bind the client named pipe in this location.
SIRIDB_HTTP_STATUS_PORT 0 When the HTTP status port is not set (or 0), the service will not start. Otherwise the HTTP requests /status, /ready and /healthy are available which can be used for readiness and liveness requests. Example usage using wget: wget -q -O - http://siridb-server.local:8080/status
SIRIDB_HTTP_API_PORT 0 When the HTTP API port is not set (or 0), the API service will not start. Otherwise the HTTP POST requests can be user to insert or query data points.
