CC Metric Router
The CCMetric router sits in between the collectors and the sinks and can be used to add and remove tags to/from traversing CCMetrics.
Configuration
{
"add_tags" : [
{
"key" : "cluster",
"value" : "testcluster",
"if" : "*"
},
{
"key" : "test",
"value" : "testing",
"if" : "name == 'temp_package_id_0'"
}
],
"delete_tags" : [
{
"key" : "unit",
"value" : "*",
"if" : "*"
}
],
"interval_timestamp" : true
}
There are three main options add_tags, delete_tags and interval_timestamp. add_tags and delete_tags are lists consisting of dicts with key, value and if. The value can be omitted in the delete_tags part as it only uses the key for removal. The interval_timestamp setting means that a unique timestamp is applied to all metrics traversing the router during an interval.
Conditional manipulation of tags
The if setting allows conditional testing of a single metric like in the example:
{
"key" : "test",
"value" : "testing",
"if" : "name == 'temp_package_id_0'"
}
If the CCMetric name is equal to 'temp_package_id_0', it adds an additional tag test=testing to the metric.
In order to match all metrics, you can use *, so in order to add a flag per default, like the cluster=testcluster tag in the example.
