Most distributions carry rsyslog in their repository. So you usually just need to use the package manager to install it. Note that on non-systemd systems (most notably Ubuntu), rsyslog usually is already installed.

QUESTION
Update: I used too many words and was not clear about what I really tried to achieve. I now edited the text to make my intentions clearer - and provide my own answer (s. below) because I successfully resolved this issue for me.
TL;DR:
Boiled down to the point, the question is:
How can I configure syslog so that some messages are routed to another service which processes them?
The question with much much more words (if you have time ;) ):
I have an integration test scenario where a Raspi would orchestrate and conduct the test. The Raspi stimulates the device under test (DUT) “from the outside” and listens for any expected reactions of the DUT. Thus, a typical integration test scenario (black box test).

Answered 2022-Mar-25 at 10:24With syslog, you can use the target with a @
notation and an IP address - then those messages would be forwarded via UDP. So all you have to do is decide on syslog facility, priority and maybe other criteria (e.g. source IP) and add in your rsyslog.conf e.g.:

Answered 2022-Mar-11 at 10:38The $FileCreateMode
parameter allows to specify the creation mode with which rsyslogd creates new files. It lets rsyslog create files with read and write access only for the users it runs under.
First, remove any restrictions for rsyslog:
QUESTION
I actually use Rsyslog 8.24 and I configured my rsyslog to accept logs from multiples input/sources.
I want to add the syslog hostname at the end of every logs.
Example :
- Old log : timestamps, header, message
- New log : timestamps, header, message syslog.domain.local
I know that the variable $myhostname or $MYHOSTNAME should return the hostname of the syslog but I don't understand how to implement this and add the syslog hostname at the end of each log.

QUESTION
I would like to print some log messages from the external check script of HAPROXY to rsyslog. For now, I use “echo” in my external-check.sh script but it does not show up the echo messages. It only shows the haproxy log messages. Is that possible?
The content of haproxy.cfg

Answered 2022-Feb-18 at 12:09I got the answer:
Currently, I am using echo
but I should use logger
to log messages from the external script to the rsyslog socket via 127.0.0.1
. By default, HAPROXY does not do it for us. It only redirects the log messages of the haproxy.cfg
events, but not the external script messages.
The trick is to replace all echo
messages by:

Answered 2022-Feb-17 at 07:06The issue was that Kibana is not automatically showing logs in the Observability/Stream.
On the top of the page there is a link to settings where you should choose log index pattern that you have created. A little unintuitive considering having that massive screaming button to add integrations.
QUESTION
I have a docker-compose with several services. The monitored processs inside one of the containers crashes from time to time and healtcheck detects this and restarts the container. Service is configured: restart: unless-stopped But there is an issue because after the restart the pid of rsyslog is not deleted and it cannot start. I can workaround this by deleting the pid in the start script before starting the rsyslog but I don't think it should behave this way. Docker container id is the same after the restart. It behaves like it has committed the container after the process crashed and then it only run the start script again. E.g. the container doesn't start cleanly but the changes made inside stay. The pid location is not a volume. I read the docker documentation on the topic - https://docs.docker.com/config/containers/start-containers-automatically/ but couldn't find anything helpful. Any idea?
...ANSWER
Answered 2022-Feb-10 at 12:08A container restart doesn't actually delete and recreate the container or its filesystem; it just restarts the main process within the existing container.
Since a container only runs one process, it's safe to unconditionally delete the pid file. I'd tend to use an entrypoint wrapper script for this:

...ANSWER
Answered 2022-Feb-04 at 12:08You can receive logs directly in elasticsearch (without even having to format them to json) through the syslog plugin. This probably would be the most straightforward solution to your problem.
If for some reason u need to use some kind of log aggregator, I personally would not recommend fluentd, as it can bring unecessary complexity with it.
But you could use logstash which is supported by elasticsearch and you can find plenty of documentation about it.
QUESTION
We have configured our application to write some specific log messages to System's Syslog file using the Syslog appender of Log4j2. No issue in writing the Syslog to the file. But when the syslog service is restarted, the first log message is not written to the syslog. The subsequent messages are written.
Enabled debug logs of Log4j, no exception is seen while writing 1st message to syslog after the restart. But for the subsequent request, the following messages were captured in the Log4j2 log.
