Yong

Yong project is system/service uptime monitor completely independent of server side softwares.

Yong is kind of system monitoring/remote administration application which help if you have lots of remote server to take care of, it can inform you if remote server or service goes down, the hotplugable prober allows you to set custom protocol based "send message", "expect message" test to make sure remote service is running OK.

For example when you ask remote web server for "GET /" , you expect the answer to contain some html codes, like < HEAD >, heres how you can do it using yong main configuration file, yong.conf which can be found in /etc/yong.conf

remote {
# server name , have to be resolved into current ip
servername=www.remote.com
# asks dns server of target for itself , make sure its alive
udp_dns_server_check=1
# asks ntp time server for time , make sure its alive
udp_ntp_server_check=1
# simple icmp echo request
icmp_echo_check=1
#
# HotPlugable Probing
# < protocol name >:< target tcp port >:"message to send":"answer to expect":< timeout >
#
# < protocol name >: this can be anything , its interval
# < target tcp port >: target tcp port of protocol , 80 for web
# "message to send": message to send for server , "GET /" for web
# "message to expect": message expected to receive , "< HEAD >" for web
# < timeout >: timeout for given session .
#
#
http:80:"GET":"HEAD":2
