-# InfluxDB Configuration
-
-The default settings provided by InfluxDB are not sufficient for a high traffic
-GitLab environment. The settings discussed in this document are based on the
-settings GitLab uses for GitLab.com, depending on your own needs you may need to
-further adjust them.
-
-## Requirements
-
-* InfluxDB 0.9 or newer
-* A fairly modern version of Linux
-* At least 4GB of RAM
-* At least 10GB of storage for InfluxDB data
-
-Note that the RAM and storage requirements can differ greatly depending on the
-amount of data received/stored. To limit the amount of stored data users can
-look into [InfluxDB Retention Policies][influxdb-retention].
-
-## InfluxDB Server Settings
-
-Since InfluxDB has many settings that users may wish to customize themselves
-(e.g. what port to run InfluxDB on) we'll only cover the essentials.
-
-### Storage Engine
-
-InfluxDB comes with different storage engines and as of InfluxDB 0.9 a new
-storage engine is available called "tsm1". All users _must_ use the new tsm1
-storage engine (this will be the default engine in upcoming InfluxDB engines).
-
-### Admin Panel
-
-Production environments should have the InfluxDB admin panel _disabled_. This
-feature can be disabled by adding the following to your InfluxDB configuration
-file:
-
-    [admin]
-      enabled = false
-
-### HTTP
-
-HTTP is required when using the InfluxDB CLI or other tools such as Grafana,
-thus it should be enabled. When enabling make sure to _also_ enable
-authentication:
-
-    [http]
-      enabled = true
-      auth-enabled = true
-
-### UDP
-
-GitLab writes data to InfluxDB via UDP and thus this must be enabled. Enabling
-UDP can be done using the following settings:
-
-    [udp]
-      enabled = true
-      bind-address = ":8089"
-      database = "gitlab"
-      batch-size = 1000
-      batch-pending = 5
-      batch-timeout = 1s
-      read-buffer = 209715200
-
-This does the following:
-
-1. Enable UDP and bind it to port 8089 for all addresses.
-2. Store any data received in the "gitlab" database.
-3. Define a batch of points to be 1000 points in size and allow a maximum of
-   5 batches _or_ flush them automatically after 1 second.
-4. Define a UDP read buffer size of 200 MB.
-
-One of the most important settings here is the UDP read buffer size as if this
-value is set too low packets will be dropped. You must also make sure the OS
-buffer size is set to the same value, the default value is almost never enough.
-
-To set the OS buffer size to 200 MB on Linux you can run the following command:
-
-    sysctl -w net.core.rmem_max=209715200
-
-To make this permanent, add the following to `/etc/sysctl.conf` and restart the
-server:
-
-    net.core.rmem_max=209715200
-
-It is **very important** to make sure the buffer sizes are large enough to
-handle all data sent to InfluxDB as otherwise you _will_ lose data. The above
-buffer sizes are based on the traffic for GitLab.com. Depending on the amount of
-traffic users may be able to use a smaller buffer size, but we highly recommend
-using _at least_ 100 MB.
-
-When enabling UDP users should take care to not expose the port to the public as
-doing so will allow anybody to write data into your InfluxDB database (as
-InfluxDB's UDP protocol doesn't support authentication). We recommend either
-whitelisting the allowed IP addresses/ranges, or setting up a VLAN and only
-allowing traffic from members of said VLAN.
