In this final part of the tutorial we will verify that all things are working properly.<\/p>\n
Because of the large number of moving components the norm is that things will go wrong. Code changes daily both in Monasca and in Openstack and quite often things need further adjusting.<\/p>\n
As a general rule, in case a component is misbehaving, change logging from INFO to DEBUG in \/etc\/monasca and restart the component. The look at the logs in \/var\/log\/monasca and see what is wrong. For Thresh \/ Storm, logs can be found in \/opt\/storm\/current\/logs<\/p>\n
<\/p>\n
In order to test if monasca-ui is properly configured log into Horizon with<\/p>\n
username: monasca\r\npassword: password\r\n<\/pre>\nAnd the monitoring panel should be visible. In case it isn’t, monasca-ui might not be getting what it expects from Keystone.<\/p>\n
In order to test monasca-api, first thing you need to do is get a valid keystone toke (let’s say for admin). Then, on a machine which has the monasca client installed run:<\/p>\n
export OS_USERNAME=monasca\r\nexport OS_PASSWORD=password\r\nexport OS_AUTH_URL=http:\/\/devstack:5000\/v3\r\nmonasca alarm-definition-list\r\n<\/pre>\nThat should return nothing as no definitions are present. Next look at some of the metrics which are being collected.<\/p>\n
