| Spawned two replicas of Prometheus to provide HA |
| |
| features: |
| - Spawned two replicas of Prometheus inside Docker Swarm. |
| These two instances have the same configuration file |
| and scrape the same endpoints. Therefore, they can be |
| treated as one-to-one copies. |
| Due to a limitation, when connecting to the Prometheus |
| web UI it is not possible to choose to which of the |
| existing Prometheus servers to connect and those |
| servers may contain slightly different results for the |
| same queries. Therefore, we suggest that you use Grafana |
| to visualize the data. |
