influxdb-docker/influxdb.conf

### Welcome to the InfluxDB configuration file.
# The values in this file override the default values used by the system if a config option is not specified. The commented out lines are the configuration field and the default value used. Uncommenting a line and changing the 
# value will change the value used at runtime when the process is restarted. Once every 24 hours InfluxDB will report usage data to usage.influxdata.com The data includes a random ID, os, arch, version, the number of series and 
# other usage data. No data from user databases is ever transmitted. Change this option to true to disable reporting. reporting-disabled = false Bind address to use for the RPC service for backup and restore. bind-address = 
# "127.0.0.1:8088"
###
### [meta]
###
### Controls the parameters for the Raft consensus group that stores metadata about the InfluxDB cluster.
###
[meta]
  # Where the metadata/raft database is stored
  dir = "/var/lib/influxdb/meta"
  # Automatically create a default retention policy when creating a database. retention-autocreate = true If log messages are printed for the meta service logging-enabled = true
###
### [data]
###
### Controls where the actual shard data for InfluxDB lives and how it is flushed from the WAL. "dir" may need to be changed to a suitable place for your system, but the WAL settings are an advanced configuration. The defaults 
### should work for most systems.
###
[data]
  # The directory where the TSM storage engine stores TSM files.
  dir = "/var/lib/influxdb/data"
  # The directory where the TSM storage engine stores WAL files.
  wal-dir = "/var/lib/influxdb/wal"
  # The amount of time that a write will wait before fsyncing.  A duration greater than 0 can be used to batch up multiple fsync calls.  This is useful for slower disks or when WAL write contention is seen.  A value of 0s fsyncs 
  # every write to the WAL. Values in the range of 0-100ms are recommended for non-SSD disks. wal-fsync-delay = "0s" The type of shard index to use for new shards.  The default is an in-memory index that is recreated at startup.  
  # A value of "tsi1" will use a disk based index that supports higher cardinality datasets. index-version = "inmem" Trace logging provides more verbose output around the tsm engine. Turning this on can provide more useful output 
  # for debugging tsm engine issues. trace-logging-enabled = false Whether queries should be logged before execution. Very useful for troubleshooting, but will log any sensitive data contained within a query. query-log-enabled = 
  # true Settings for the TSM engine CacheMaxMemorySize is the maximum size a shard's cache can reach before it starts rejecting writes. Valid size suffixes are k, m, or g (case insensitive, 1024 = 1k). Vaues without a size 
  # suffix are in bytes. cache-max-memory-size = "1g" CacheSnapshotMemorySize is the size at which the engine will snapshot the cache and write it to a TSM file, freeing up memory Valid size suffixes are k, m, or g (case 
  # insensitive, 1024 = 1k). Values without a size suffix are in bytes. cache-snapshot-memory-size = "25m" CacheSnapshotWriteColdDuration is the length of time at which the engine will snapshot the cache and write it to a new TSM 
  # file if the shard hasn't received writes or deletes cache-snapshot-write-cold-duration = "10m" CompactFullWriteColdDuration is the duration at which the engine will compact all TSM files in a shard if it hasn't received a 
  # write or delete compact-full-write-cold-duration = "4h" The maximum number of concurrent full and level compactions that can run at one time.  A value of 0 results in 50% of runtime.GOMAXPROCS(0) used at runtime.  Any number 
  # greater than 0 limits compactions to that value.  This setting does not apply to cache snapshotting. max-concurrent-compactions = 0 The maximum series allowed per database before writes are dropped.  This limit can prevent 
  # high cardinality issues at the database level.  This limit can be disabled by setting it to 0. max-series-per-database = 1000000 The maximum number of tag values per tag that are allowed before writes are dropped.  This limit 
  # can prevent high cardinality tag values from being written to a measurement.  This limit can be disabled by setting it to 0. max-values-per-tag = 100000
###
### [coordinator]
###
### Controls the clustering service configuration.
###
[coordinator]
  # The default time a write request will wait until a "timeout" error is returned to the caller. write-timeout = "10s" The maximum number of concurrent queries allowed to be executing at one time.  If a query is executed and 
  # exceeds this limit, an error is returned to the caller.  This limit can be disabled by setting it to 0. max-concurrent-queries = 0 The maximum time a query will is allowed to execute before being killed by the system.  This 
  # limit can help prevent run away queries.  Setting the value to 0 disables the limit. query-timeout = "0s" The time threshold when a query will be logged as a slow query.  This limit can be set to help discover slow or 
  # resource intensive queries.  Setting the value to 0 disables the slow query logging. log-queries-after = "0s" The maximum number of points a SELECT can process.  A value of 0 will make the maximum point count unlimited.  This 
  # will only be checked every second so queries will not be aborted immediately when hitting the limit. max-select-point = 0 The maximum number of series a SELECT can run.  A value of 0 will make the maximum series count 
  # unlimited. max-select-series = 0 The maxium number of group by time bucket a SELECT can create.  A value of zero will max the maximum number of buckets unlimited. max-select-buckets = 0

###
### [shard-precreation]
###
### Controls the precreation of shards, so they are available before data arrives. Only shards that, after creation, will have both a start- and end-time in the future, will ever be created. Shards are never precreated that would 
### be wholly or partially in the past.

  # Determines whether shard pre-creation service is enabled. enabled = true The interval of time when the check to pre-create new shards runs. check-interval = "10m" The default period ahead of the endtime of a shard group that 
  # its successor group is created. advance-period = "30m"
###
### Controls the system self-monitoring, statistics and diagnostics.
###
### The internal database for monitoring data is created automatically if if it does not already exist. The target retention within this database is called 'monitor' and is also created with a retention period of 7 days and a 
### replication factor of 1, if it does not exist. In all cases the this retention policy is configured as the default for the database.

###
### [logging]
###
### Controls how the logger emits logs to the output.
###
[logging]
  # Determines which log encoder to use for logs. Available options are auto, logfmt, and json. auto will use a more a more user-friendly output format if the output terminal is a TTY, but the format is not as easily 
  # machine-readable. When the output is a non-TTY, auto will use logfmt. format = "auto" Determines which level of logs will be emitted. The available levels are error, warn, info, and debug. Logs that are equal to or above the 
  # specified level will be emitted. level = "info" Suppresses the logo output that is printed when the program is started. The logo is always suppressed if STDOUT is not a TTY. suppress-logo = false

  # udp-read-buffer = 0
  ### This string joins multiple matching 'measurement' values providing more control over the final measurement name.
  # separator = "."
  ### Default tags that will be added to all metrics.  These can be overridden at the template level or by tags extracted from metric
  # tags = ["region=us-east", "zone=1c"]
  ### Each template line requires a template pattern.  It can have an optional filter before the template and separated by spaces.  It can also have optional extra tags following the template.  Multiple tags should be separated 
  ### by commas and no spaces similar to the line protocol format.  There can be only one default template.
