Ingest Listeners are not available on Humio Cloud. You will have to run your own on premises Humio cluster to use Ingest Listeners.
Ingest listeners are a great way of shipping data to Humio through raw sockets, using either UDP or TCP. Example use cases are:
An ingest listener binds a UDP or TCP port on an network interface to a repository with a parser. All data sent to a network port will be parsed before it’s inserted into the repository.
Go to the Ingest Listeners subpage in your repository’s settings page to see a list of already configured ingest listeners. For a new installation this list will be empty.
In the upper right hand corner there’s a button for Creating a New Ingest Listener
Creating a new ingest listener is all about mapping a port on a network interface through a parser to a repository. Selecting Add Ingest Listener will present you with the following form:
The ingest listener needs the following details
--net=hostthis port needs to be exposed via
To reduce packet loss in bursts of UDP traffic, please increase the maximum allowed receive buffer size for UDP.
Humio will try to increase the buffer to up to 128MB, but will accept whatever the system sets as maximum.
# Get the current limit from the kernel (in bytes) sysctl net.core.rmem_max # Set to 16MB. Decide on a value of (say) 0.5 - 2 seconds worth of inbound UDP packets. sudo sysctl net.core.rmem_max=16777216
Note that this change needs to happen before Humio is started. You
probably want it done when the system boots. On Debian (e.g. Ubuntu)
you can achieve this by creating a file in
/etc/sysctl.d/ with a
name such as
raise_rmem_max.conf and the contents
