# 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](../ccMetric/README.md).
|
|
|
|
# Configuration
|
|
|
|
```json
|
|
{
|
|
"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:
|
|
|
|
```json
|
|
{
|
|
"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.
