Adding syslog-ng to a host to extract Nginx logs

Leave a Comment / FreeBSD, Monitoring, Open Source, syslog-ng, Victoria Logs / By /

This replaces and combines two earlier posts: Replacing syslogd with syslog-ng (sysutils/syslog-ng) on FreeBSD. Getting Nginx logs into Victoria-Logs I just got Victoria Logs running. Now I want to get logs into it. For starters, I want to get the logs on the host itself into Victoria Logs. I figure this is a log-risk experiment. In this post: FreeBSD 15.0 victoria-logs-1.50.0_2 syslog-ng-4.11.0_2 I’m installing syslog-ng on a host (x8dtu) The nginx logs reside […]

Getting Nginx logs into Victoria-Logs – v2

Leave a Comment / FreeBSD, Monitoring, nginx, Open Source, syslog-ng, Victoria Logs / By /

VictoriaLogs is feature rich, which means at this point, I know very little about it. However, this post has been deprecated by a newer post which covers more material. I do know that the original syslog-ng configuration I supplied in Getting Nginx logs into Victoria-Logs is now less complicated. With the help of duck.ai, I managed to reduce it. Now it’s sending the json without running it through a parser. In this post:

VictoriaLogs: Adding syslog-ng to a host and ingesting nginx log from jails

Today I’ll start pulling production FreshPorts nginx logs into VictoriaLogs. Over the past few days, I’ve configured a proof-of-concept and now I’m ready to try this in prod.

Getting Nginx logs into Victoria-Logs

My goal today: get nginx logs into Victoria-Logs. I’ve already gotten Victoria-Logs running on FreeBSD and replaced syslog with syslog-ng to get TLS NOTE: This post was originally only about Nginx. I’ve since added general syslog messages to the configuration. However, this post has been deprecated by a newer post which covers more material. Also, the Adding an nginx proxy in front of Victoria-Labs post might be helpful before proceeding here. Over the

Adding an nginx proxy in front of Victoria-Labs

Victoria-Logs has an built-in UI – and it’s easier for me to access via my web browser if I put Nginx in front of it.

I’ve done that above to make it easier for you to read. Nginx This

LibreNMS 26.6.0 & itable cache directories vntl/var/db/

I updated my version of LibreNMS to 26.6.0 and there are “decent sized refactor to the rrd processes” – I’m seeing the following: This is an issue with fontconfig The advice I was given: “XDG_CACHE_HOME might help, but I’m not sure if that is the right fix…” I first created a new directory (I’ve since discovered creating the directory is not necessary, adding the configuration item is sufficient): [12:45 besser dvl /var/db/librenms] %

Getting Victoria Logs running on FreeBSD

Leave a Comment / FreeBSD, Open Source / By /

This post is only about getting Victoria Logs running on FreeBSD. A future post will go over configuration and getting logs in. I’m hoping Victoria Logs can fill the role which ElasticSearch once tried to fill, but failed; it was too finicky and fragile for my use. In this post: FreeBSD 15.0 victoria-logs-1.50.0_2 mkjail-0.0.8 Jail creation I’m going to run this in a jail, like most things. You don’t have to. I’m using

Today, about a nearly two weeks after making some config changes for some Let’s Encrypt certs, today I saw new-to-me messages: In this post: FreeBSD 15.0 acme.sh-3.1.3_1 Looking up that URL, I found: Let’s see: root@certs:/var/db/acme/certs # host acme-v02.api.acmeencrypt.org Host acme-v02.api.acmeencrypt.org not found: 3(NXDOMAIN) root@certs:/var/db/acme/certs # Oh. I posted on Mastodon before proceeding. First things first. Priority matters. Then I went into /var/db/acme/certs/r720-02-pg01.example.org/r720-02-pg01.example.org.conf and made this change: In short, acmeencrypt became letsencrypt. I

Giving poudriere a jump start

From time to time, I build my ports for a different version of MySQL, or Python, or, as in tonights case, PHP. My usual build command is: [23:43 pkg01 dvl ~] % sudo poudriere bulk -j 150amd64 -p default -z primary -f /usr/local/etc/poudriere.d/buildlists/primary In this post: FreeBSD 15.0 poudriere-3.4.8 For me to build against PHP85, I first created this file: [23:56 pkg01 dvl /usr/local/etc/poudriere.d] % cat 150amd64-default-php85-make.conf DEFAULT_VERSIONS+= php=85 With that file in
