Alarm on receiveBufferSize not trigered on Gelf Udp input #1243
Comments
Sorry, we cannot execute sysctl commands when installing a package. If you run network software with different protocols, you have to be aware of tuning the network stack of your machines. |

@rlanore There will be a warning for UDP inputs as well in the upcoming version. |
Get the same warning log like this: Maybe graylog should show “warning message” in input modal when setting SO_RCVBUF > net.core.rmem_max. |

When you start an GELF UDP input there are no alarm like GELF TCP input:
2015-06-10T11:50:54.161Z WARN [NettyTransport] receiveBufferSize (SO_RCVBUF) for [id: 0xe574613f, /0.0.0.0:12202] should be 1048576 but is 131071.
it's important to identify problem for event lost
and they are no documentation this.
Graylog installed from deb package must doing this
sysctl -w net.core.rmem_max=1048576
