Monitor Linux servers
The Monitorpack team regularly provides useful metrics to easily monitor your applications, devices and systems. These are basic measurements, if you want to go further Monitorpack software Guard is able to check all performance counters, services, processes, ports, event IDs, existing printers and shares in your IT environment.
Linux prerequisites
In order for Monitorpack Guard to be able to remotely control Linux without deploying agents, two prerequisites are necessary, the first is that the Linux server must respond to the ping and therefore accept it. Here is the command to apply on Debian in order to authorize the ping:
sudo ufw status
sudo ufw allow icmp
sudo nano /etc/sysctl.conf
net.ipv4.icmp_echo_ignore_all = 0
net.ipv4.icmp_echo_ignore_broadcasts = 0
sudo sysctl -p
The second prerequisite is obviously that SNMP is enabled and accepts remote requests, including that the specific community must also be configured. To configure snmp on Linux, you must first install the snmpd package with the command:
Command to Activate SNMP on Debian 11
Load and instal the SNMP packageor rocommunity "community name" "ip range (unique ip) /subnet mask, ex:"
# rocommunity public default -V systemonly
Update with your specific commity name like rocommunity 'MyCommunityname'
