openNAC Trending¶
To check openNAC performance and its trend you have to go to Status -> Trending, as shown at the step 1 and step 2.
In case we have a distributed deployment with many different nodes, per node trending, performance and graphs are also available.
All the information is stored in DDR Files, this increase graphs calculation and system response.
Time Ranges are available, allowing use to select:
1H: 1 hour time range.
2H: 2 hours time range.
8H: 8 hours time range.
1W: 1 week time range.
1M: 1 moth time range.
1Q: 1 Quarter time range.
1Y: 1 Year time range.
Different section graphs are available, plenty of information is shown in every picture.
CPU: Graphs regarding CPU usage.
openNAC: Graphs regarding openNAC services.
Disk: Graphs regarding openNAC disks.
Interface: Graphs regarding interfaces.
Load: Graphs regarding system components load.
Memory: Graphs regarding memory use.
MySQL: Graphs regarding database component.
Active Directory: Graphs regarding Active Directory sub-component.
Redis: Graphs regarding Redis component.
Conntrack: Graphs regarding Conntrack component.
If we go to the step 1 is shown trending about Active Directory, at step 2 a 1M (1 month time range) is selected. For instance is shown Connection per second against the active directory.
