记录influxdb缺省配置, 目的一方面是为了记录配置的解释, 一方面是为了以后修改配置的核对.
influxdb缺省配置:
生成缺省配置文件命令:
influxd config > influxdb.confinfluxdb.conf 文件内容:
### 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
# Provides more error checking. For example, SELECT INTO will err out inserting an +/-Inf value
# rather than silently failing.
# strict-error-handling = false
# Validates incoming writes to ensure keys only have valid unicode characters.
# This setting will incur a small overhead because every key must be checked.
# validate-keys = false
# 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).
# Values 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
# CompactThroughput is the rate limit in bytes per second that we
# will allow TSM compactions to write to disk. Note that short bursts are allowed
# to happen at a possibly larger value, set by CompactThroughputBurst
# compact-throughput = "48m"
# CompactThroughputBurst is the rate limit in bytes per second that we
# will allow TSM compactions to write to disk.
# compact-throughput-burst = "48m"
# If true, then the mmap advise value MADV_WILLNEED will be provided to the kernel with respect to
# TSM files. This setting has been found to be problematic on some kernels, and defaults to off.
# It might help users who have slow disks in some cases.
# tsm-use-madv-willneed = false
# Settings for the inmem index
# 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
# Settings for the tsi1 index
# The threshold, in bytes, when an index write-ahead log file will compact
# into an index file. Lower sizes will cause log files to be compacted more
# quickly and result in lower heap usage at the expense of write throughput.
# Higher sizes will be compacted less frequently, store more series in-memory,
# and provide higher write throughput.
# Valid size suffixes are k, m, or g (case insensitive, 1024 = 1k).
# Values without a size suffix are in bytes.
# max-index-log-file-size = "1m"
# The size of the internal cache used in the TSI index to store previously
# calculated series results. Cached results will be returned quickly from the cache rather
# than needing to be recalculated when a subsequent query with a matching tag key/value
# predicate is executed. Setting this value to 0 will disable the cache, which may
# lead to query performance issues.
# This value should only be increased if it is known that the set of regularly used
# tag key/value predicates across all measurements for a database is larger than 100. An
# increase in cache size may lead to an increase in heap usage.
series-id-set-cache-size = 100

###
[coordinator]
# The default time a write request will wait until a "timeout" error is returned to the caller.

# by setting it to 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.

### 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
