Now – around this same time Loki 2.0 was released. Within a few minutes I had all of my hosts streaming Syslog from my network into Loki and explorable within Grafana! The relabeling in Promtail takes the hostname of the sending device into syslog-ng and turns it into a host label for Loki to index.

(Many of my devices only output the older style of Syslog…) A few quick configurations was I needed to do to get syslog-ng and Promtail talking to each other! syslog-ng Configuration # nf What’s useful about syslog-ng in my situation is that it can be spun up to listen for RFC3164 (UDP port 514) and then forward it to Promtail RFC5424 on port 1514. For me, I jumped into docker-compose (even with Loki’s roots coming from Prometheus and Kubernetes – I’m looking to build out essentially a quick start standalone Syslog ingester.)Ī look through some of the Loki documentation on configuring Promtail with Syslog had me realize that Promtail only works with IETF Syslog (RFC5424) – which is how I also found out my devices were limited to only RFC3164. One of the primary ways to get logs into Loki is with the use of Promtail, also easily deployed the same way. Loki is actually quite easy to deploy as single binary either via the command line or in Docker. And so I set out to see what I could accomplish. Presented with an amazing way to discover and consume logs in relationship to Prometheus and Kubernetes with microservices – it didn’t immediately occur to me to capture standalone network logs with Loki in this same fashion. My first exposure to Loki came recently during my first days at Grafana Labs. This now becomes a tale of how I came to love logs. What I really needed was some Open Source goodness. I needed to collect data from more than a dozen systems and I’m running on Linux and MacOS.
#DOCKER SYSLOG NG FREE#
Most of the attention grabbing “6 Free Syslog Servers” links turned into a fair number of Windows utilities but each still pretty limited to just a few hosts at a time. But all I had to work with was Syslog.Ī search on Google for “Syslog Collector” presented me 342,000 results to start my effort. My initial challenge to tackle involved understanding why my wireless devices were having intermittent network instability and which (if any) of my wireless access points were having the most number of issues. And two, I have a handful of home lab servers, an increasingly complex network, and storage devices that are hard to see what they’re doing all the time. One, I discovered Loki, Grafana’s log aggregation system. Do you remember the days of creating shared NAS exports and just writing out logs until they filled up? (Yeah – me neither… ahem…) But recently two things have come to light in the last few months that make this hopefully an interesting story to tell. That’s not to say I haven’t combed through my fair share of application logs across hundreds of end points. Almost to a fault – I largely ignored logs. What could be wrong? Sorry if information is a bit too scarce.I’ll be the first to admit that I’ve always been a metrics person. The client is trying to send logs in TCP, but it seems to me that the server is dumping them for some strange reason?
#DOCKER SYSLOG NG DRIVER#
NOTE: the client is sending logs with the same syslog() driver used by the server, so it’s not an issue of wrong driver used.

My nf configuration file is this: "scl.conf" T19:50:01+01:00 ip-client systemd: Started Session 1540 of user root. T19:49:10+01:00 ip-client syslog-ng: EOF occurred while idle fd='8' –this is the output of the file logs.txt. The problem here is that the logs inside the file are all like this: So, the situation here is that i have a syslog-ng version 3.24 custom container, based on the Ubuntu:18.04 image, which should accept connections on port 514 in TCP, and after that it saves the logs in a file called “logs.txt”. I am sorry for my bad writing but this is my first question.
