Script for monitoring Xen/XenServer Dom0 and more

Prerequisites

Installing git

XCP 8

yum install git

XenServer 7.2

yum --enablerepo base install git

Installing Zabbix agent

XCP 8

rpm -Uvh https://repo.zabbix.com/zabbix/6.4/rhel/7/x86_64/zabbix-release-6.4-1.el7.noarch.rpm
rpm -Uvh http://mirror.centos.org/centos/7/os/x86_64/Packages/pcre2-10.23-2.el7.x86_64.rpm

Configuring IPtables

vi /etc/sysconfig/iptables

add line (before REJECT)

# Zabbix-Agent
-A RH-Firewall-1-INPUT -m conntrack --ctstate NEW -m tcp -p tcp --dport 10050 -j ACCEPT

restart iptables

systemctl stop iptables
systemctl start iptables

Configure Zabbix Agent to use PSK (pre-shared key)

generate a PSK:

sh -c "openssl rand -hex 32 > /etc/zabbix/zabbix_agentd.psk"

aggiungere PSK alla configurazione dell'agente

vi /etc/zabbix/zabbix_agentd.conf

modificare:

Server=host.domain
TLSConnect=psk
TLSAccept=psk
TLSPSKIdentity=<unique_id>
TLSPSKFile=/etc/zabbix/zabbix_agentd.psk

configurare la stessa chiave/identità in zabbix

Cloning repo

cd /opt/
git clone https://github.com/rivoduck/zabbix_monitoring_scripts.git

Install scripts

cd /opt/zabbix_monitoring_scripts
./install.sh

nel file /etc/sudoers commentare le linee (quelle presenti)

Defaults    requiretty

Defaults    use_pty

aggiungere la linea in fondo

zabbix ALL=(ALL) NOPASSWD: ALL

Install StorCLI

for intel RAID controllers

Docker compose monitoring scripts

Script for monitoring docker compose project

• docker_compose_container_discovery.sh: Monitor the state of containers by grouping them based on the Compose project
• docker_project_discovery.sh: Performs discovery of Compose projects
• compose_status.sh: Creates items with the status of Compose projects.

Project grouping: Swarm support and custom override

Discovery works out of the box on both Docker Compose and Docker Swarm. On Compose nodes containers are grouped by the standard com.docker.compose.project label; on Swarm nodes they are grouped by com.docker.stack.namespace, the label that Swarm assigns automatically to every container of a stack. No configuration is required for either case.

In addition, a container can opt into a custom grouping by setting the zabbix.docker.project label. When present, this label takes precedence over the auto-detected one. This is useful to split a single project (Compose or Swarm) into multiple logical sub-projects, or to merge containers from different projects into the same bucket by giving them the same value.

Containers that carry none of these labels continue to fall into the no-docker-compose-project bucket as before.

Priority order (first non-empty match wins):

1. zabbix.docker.project — opt-in custom label
2. com.docker.compose.project — Docker Compose default
3. com.docker.stack.namespace — Docker Swarm default
4. no-docker-compose-project — fallback bucket (unchanged)

Example — split a compose project into two logical sub-projects:

services:
  api:
    labels:
      zabbix.docker.project: "myapp-backend"
  db:
    labels:
      zabbix.docker.project: "myapp-data"
  redis:
    labels:
      zabbix.docker.project: "myapp-data"

Zabbix will discover two separate projects (myapp-backend, myapp-data) instead of a single aggregate.

Template files

The template directory contains the templates related to the scripts to be added to Zabbix:

• zbx_topix_docker_compose_container_status.xml: Discovery of Docker containers and Compose projects.
• zbx_topix_docker_compose_status.xml: Compose Project Status Monitoring.

Configuration to be added to zabbix_agent2.conf
