check_ipsec
Checks vpn connection status of an openswan or strongswan installation.
Usage: check_ipsec --tunnels
./check_ipsec --tunnels 10 OK - All 10 tunnels are up an running
You have to run this plugin with nrpe. Add these lines to /etc/sudoers:
Cmnd_Alias IPSEC = /usr/lib/nagios/plugins/check_ipsec nagios ALL=NOPASSWD:IPSEC
Core pre-req requirement not mentioned: FPING Ubuntu16 instance had to modify the FPING path to usrinfping (not usrsbinfping) Also had to modify the grep string check for the latest strongSwan tunnel check: ORIGINAL: tunneltest=`$IPSECBIN status | grep -e "IPsec SA established" | grep -e "newest IPSEC" |grep -e $CONN | wc -l` UPDATED: tunneltest=`$IPSECBIN status | grep -e "ESTABLISHED" | wc -l` Suggest using full path in GATEWAYLIST variable instead of relative path and just a filename. Works effectively once tweaked for the deployed environment.
