DNS General Indicators
The DNS General Indicators dashboard element rendered as a table shows the server state, its last and startup reload time, the number of zones per server, and the total resource record (RR) count. The table is available if you choose DNS Metrics: DNS General Indicators in the Chart Selections page.
The resulting table shows:
- Server State —Up or Down (based on whether statistics are available), and how long the server has been in this state.
- Last Reload —How long since the last server reload.
- Total Zones —Number of configured zones.
- Total RRs —Number of resource records.
How to Interpret the Data
The data in this chart shows general server health and operational duration. The objective is to make decisions about the server, such as whether it might be time for another reload, perhaps warranted by the number of configured zones.
Troubleshooting Based on the Results
If the server state is Down, all the DNS chart indicators show a red status box, so no data will be available. In the case of a server that is down, restart the server. The number of zones indicated might also require some evaluation and possible reconfiguration.
