So, the last few weeks my colleagues and myself have been noticing that there has been a couple of issues with the cloud-servers servicenet interface. Unfortunately for some customers utilizing dbaas instances this means that their cloud-server will be unable to communicate, often, with their database backend.<\/p>\n
The solution is a custom monitoring script that my colleague Marcin has kindly put together for another customer of his own.<\/p>\n
The python script that goes on the server:<\/p>\n
Create file:<\/p>\n
\r\nvi \/usr\/lib\/rackspace-monitoring-agent\/plugins\/servicenet.sh\r\n<\/pre>\nPaste into file:<\/p>\n
\r\n#!\/bin\/bash\r\n#\r\nping=\"\/usr\/bin\/ping -W 1 -c 1 -I eth1 -q\"\r\n\r\nif [ -z $1 ];then\r\n echo -e \"status CRITICAL\\nmetric ping_check uint32 1\"\r\n exit 1\r\nelse\r\n $ping $1 &>\/dev\/null\r\n if [ \"$?\" -eq 0 ]; then\r\n echo -e \"status OK\\nmetric ping_check uint32 0\"\r\n exit 0\r\n else\r\n echo -e \"status CRITICAL\\nmetric ping_check uint32 1\"\r\n exit 1\r\n fi\r\nfi\r\n\r\n<\/pre>\nCreate an alarm that utilizes the below metric<\/p>\n
\r\nif (metric[\"ping_check\"] == 1) {\r\n return new AlarmStatus(CRITICAL, 'what?');\r\n}\r\nif (metric[\"ping_check\"] == 0) {\r\n return new AlarmStatus(OK, 'eee?');\r\n}\r\n<\/pre>\nOf course for this to work the primary requirement is a Rackspace Cloud-server and an installation of Rackspace Cloud Monitoring installed on the server already. <\/p>\n
Thanks again Marcin, for this golden nugget.<\/p>\n","protected":false},"excerpt":{"rendered":"
