title: How can I transfer logs from Logs Viewer of GCP to Slack or email?
body: <p>I have been exploring to transfer the <code>JsonPayload message field</code> from Logs viewer service  <strong>(which are syslogs of a service)</strong> of GCP to a slack network, but owing to this I am not able to find any predefined services <strong>(like alerting policies to transfer Payload)</strong> available on Stackdriver. I have been able to create a counter or distribution user-metrics for logs but this will only provide me with some int64 value instead of a string value or the actual message body. Is there a way <code>in GCP</code> to actually send a payload of logs over slack or any email?</p>
