Added new IPFire specific monitoring capabilities to Zabbix Agent: - ipfire.ovpn.clients.discovery: Discovery of configured ovpn clients. Returns a JSON array. - ipfire.ovpn.statusreport.get: Parses and returns /var/run/ovpnserver.log in a JSON array
Since /var/run/ovpnserver.log is only readable by root, 'cat' of that file is added to sudoers.d/zabbix_agentd. --- config/zabbix_agentd/sudoers | 2 +- config/zabbix_agentd/userparameter_ipfire.conf | 8 +++++++- 2 files changed, 8 insertions(+), 2 deletions(-)
