The `solarwinds` adapter enables Istio to deliver log and metric data to the Papertrail logging backend and the AppOptics monitoring backend.

        solarwindslogentry.logentry.istio-system:
          payloadTemplate: '{{or (.originIp) "-"}} - {{or (.sourceUser) "-"}} [{{or (.timestamp.Format "2006-01-02T15:04:05Z07:00") "-"}}] "{{or (.method) "-"}} {{or (.url) "-"}} {{or (.protocol) "-"}}" {{or (.responseCode) "-"}} {{or (.responseSize) "-"}}'

Field | Type | Description
--- | --- | ---
`appopticsAccessToken` | `string` | AppOptics Access Token needed to send metrics to AppOptics. If no access token is given then metrics will NOT be shipped to AppOptics
`appopticsBatchSize` | `int32` | Optional. Max batch size of metrics to be sent to AppOptics. AppOptics does not allow batch size greater than 1000. If this is unspecified or given a value 0 explicitely, a default batch size of 1000 will be used.
`papertrailUrl` | `string` | Papertrail url to ship logs to. If no papertrail url is given then the logs will NOT be shipped but rather dropped.
`papertrailLocalRetentionDuration` | `google.protobuf.Duration` | This is the duration for which logs will be persisted locally until it is shipped to papertrail in the event of a network failure. Default value is 1 hour.
`metrics` | `map<string, Params.MetricInfo>` | A map of Istio metric name to solarwinds metric info.
`logs` | `map<string, Params.LogInfo>` | A map of Istio logentry name to solarwinds log info.

## Params.LogInfo

Describes how to represent an Istio log entry in Solarwinds AppOptics

Field | Type | Description
--- | --- | ---
`payloadTemplate` | `string` | Optional. A golang text/template template (more details about golang text/template’s templating can be found here: https://golang.org/pkg/text/template/) that will be executed to construct the payload for this log entry. An example template that could be used: {{or (.originIp) “-”}} - {{or (.sourceUser) “-”}} [{{or (.timestamp.Format “2006-01-02T15:04:05Z07:00”) “-”}}] “{{or (.method) “-”}} {{or (.url) “-”}} {{or (.protocol) “-”}}” {{or (.responseCode) “-”}} {{or (.responseSize) “-”}} A sample log that will be created after parsing the template with appropriate variables will look like this: Jan 23 21:53:02 istio-mixer-57d88dc4b4-rbgmc istio: 10.32.0.15 - kubernetes://istio-ingress-78545c5bc9-wbr6g.istio-system [2018-01-24T02:53:02Z] “GET /productpage http” 200 5599 It will be given the full set of variables for the log to use to construct its result. If it is not provided, a default template in place will be used.

## Params.MetricInfo

Describes how to represent an Istio metric in Solarwinds AppOptics

Field | Type | Description
--- | --- | ---
`labelNames` | `string[]` | The names of labels to use: these need to match the dimensions of the Istio metric.
