signalfx adapter collects Istio metrics and trace spans and sends them
If sending trace spans, this adapter can make use of certain conventions in the tracespan format that is configured to send to this adapter. Here is an example tracespan spec that will work well:
apiVersion: config.istio.io/v1alpha2 kind: instance metadata: name: signalfx spec: compiledTemplate: tracespan params: traceId: request.headers["x-b3-traceid"] | "" spanId: request.headers["x-b3-spanid"] | "" parentSpanId: request.headers["x-b3-parentspanid"] | "" # If the path contains query parameters, they will be split off and put into # tags such that the span name sent to SignalFx will consist only of the path # itself. spanName: request.path | "/" startTime: request.time endTime: response.time # If this is >=500, the span will get an 'error' tag httpStatusCode: response.code | 0 clientSpan: context.reporter.kind == "outbound" # Span tags below that do not have comments are useful but optional and will # be passed to SignalFx unmodified. The tags that have comments are interpreted # in a special manner, but are still optional. spanTags: # This is used to determine whether the span pertains to the client or # server side of the request. context.reporter.local: context.reporter.local # This gets put into the remoteEndpoint.ipv4 field destination.ip: destination.ip | ip("0.0.0.0") # This gets flattened out to individual tags of the form # 'destination.labels.<key>: <value>'. destination.labels: destination.labels # This gets put into the remoteEndpoint.name field destination.name: destination.name | "unknown" destination.namespace: destination.namespace | "unknown" request.host: request.host | "" request.method: request.method | "" request.path: request.path | "" request.size: request.size | 0 request.useragent: request.useragent | "" response.size: response.size | 0 # This gets put into the localEndpoint.name field source.name: source.name | "unknown" # This gets put into the localEndpoint.ipv4 field source.ip: source.ip | ip("0.0.0.0") source.namespace: source.namespace | "unknown" # This gets flattened out to individual tags of the form # 'source.labels.<key>: <value>'. source.labels: source.labels source.version: source.labels["version"] | "unknown"
Configuration format for the
Describes what metrics should be sent to SignalFx and in what form.
Describes what kind of metric this is.
None is the default and is invalid
Values with the same set of dimensions will be added together as a continuously incrementing value.
A histogram distribution. This will result in several metrics emitted for each unique set of dimensions.
