| // Package tsmon adapts common/tsmon library to GAE environment. |
| // |
| // It configures tsmon state with a monitor and store suitable for GAE |
| // environment and controls when metric flushes happen. |
| // |
| // Timeseries metrics are gathered automatically by the tsmon middleware and |
| // staged in memory for export. Periodically, an unlucky single handler will |
| // be chosen to perform this export at the end of its operation. |
| // |
| // A cron task MUST also be installed if metrics are enabled. The task assigns |
| // and manages the task number assignments for active instances. If this cron |
| // task is not installed, instances will not get IDs and will be unable to send |
| // metrics. The cron task should be configured to hit: |
| // "/internal/cron/ts_mon/housekeeping" every minute. |
