Hystax Acura Grafana Dashboards: Reading Replication & Health Metrics

Interpreting replication and performance data with Grafana

Task

How to interpret data using Grafana.

Solution

To access the Grafana dashboards log in at http://<ACURA_IP>:30082.

On the Home Dashboard page find:
  1. the list of useful dashboards
  2. global replication speed and network utilization.


We’ve starred 3 dashboards for your usability. Find them on the left panel of the Home Dashboard: the stats for customers, devices, and snapshots. They include a set of panels:
  1. “Data Block Flow” measures replication speed, with a breakdown of block types

  1. “Network Utilization” measures real network traffic (currently only between Replication Agent and Acura, without Cloud Agent traffic)

  1. “Receiver Operation Breakdown” measures the percent of time the Receiver spent doing its operations. This is useful for finding bottlenecks:
    1. If the Receiver spends most of the time waiting for input, it means the Replication Agent can’t read or send fast enough.
    2. If the Receiver spent most of the time on storage processing, it means the Cloud Agent can’t receive or write fast enough.

  1. “Replication agent → Receiver Bandwidth optimization” metric measures how much network traffic was saved through compression and WAN optimization

  1. “Processing speed” measures the speed of individual Receiver and Replication Agent operations

  1. “Receiver threads” measure how many threads in the Receiver are active
