Hi everyone,
I got an old disk containing my old influxdb server
i mounted it and tried to integrate it with my new influx server
so i tried to add the old /var/influxdb/data and /var/influxdb/wal with my new ones then u checked and i found that the old influxdabases was addes to the list of my new databases ! that was cool but after a hours i found that error "Failed to connect to http://localhost:8086: Get http://localhost:8086/ping: dial tcp [::1]:8086: connect: connection refused
Please check your connection settings and ensure ‘influxd’ is running.
“”
and when i try netstat i couldn’t find 8086 port listen !
/etc/influxdb/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
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

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

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 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 maximum number of group by time bucket a SELECT can create. A value of zero will max the maximum

log-enabled = true
Determines whether the HTTP write request logs should be suppressed when the log is enabled.
suppress-write-log = false
When HTTP request logging is enabled, this option specifies the path where
log entries should be written. If unspecified, the default is to write to stderr, which
intermingles HTTP logs with internal InfluxDB logging.
If influxd is unable to access the specified path, it will log an error and fall back to writing
the request log to stderr.
access-log-path = “”
Filters which requests should be logged. Each filter is of the pattern NNN, NNX, or NXX where N is
a number and X is a wildcard for any number. To filter all 5xx responses, use the string 5xx.
If multiple filters are used, then only one has to match. The default is to have no filters which
will cause every request to be printed.

write-tracing = false
Determines whether the pprof endpoint is enabled. This endpoint is used for
troubleshooting and monitoring.

enqueued-write-timeout = 0
[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.

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.
