Assurance

2.1.d i Network and client health (360)

General information on “SDA Network and client health (360)":

Visible under Assurance -> Dashboards -> Health -> Overall Health
Shows the overall and per-device health of all network devices (routers/switches/…), wired and wireless clients
Opening a single device provides “a 360 view” including:
- Issues: Shows if there are current issues.
- Physical Neighbor Topology: Shows the physical connection of the device within the fabric.
- Event Viewer: Records syslog events of Error and above (Emergency, Alert, Critical).
- Path Trace Application: Shows the path between a source/destination. Also displays possible path errors (eg. ACLs blocking traffic, …).
- Application Experience: Measure of application performance. Only available for routers/clients.
- Detailed Information: Shows device-specific information like CPU, memory, interface usage, etc.
When opening the “360 view” of a single device, a timeline is shown
Within the timeline, a specific timestamp or range can be selected to show information on what happened at that timestamp/range
It is possible to back up to 14 days in the timeline (= maximum information storage time)
The health score per device is measured between 0 and 10 points and is represented with colors:
- Red: Critical issues. Health score is between 1 and 3.
- Orange: Warnings. Health score is between 4 and 7.
- Green: No errors/warnings. Health score is between 8 and 10.
- Grey: No data available. Health score is 0.

General information on “SDA Monitoring and troubleshooting”:

For monitoring/troubleshooting to be possible the device must have been added to a fabric site and SNMP collectors need to be enabled
DNAC monitors all issues happening within the network (network devices and clients) and classifies them based on their impact
DNAC Assurance issue classification:
- P1: Critical issue which needs immediate attention and can impact the whole network.
- P2: Major issue which can potentially impact multiple devices/clients.
- P3: A minor issue with local or minimal impact.
- P4: A warning issue that may not be a problem but addressing it can optimize the network performance.
This behavior can be modified under Assurance -> Manage -> Issue Settings
It’s possible to change the issue classification based on the own needs as well as turning off detection for issues completely
When clicking on an issue, DNAC provides suggested action which may lead to resolving it
The last provided option is always “Contact Cisco TAC for support”
Within an issue, the status can be changed to RESOLVED or IGNORE:
- When changing the status to RESOLVED, the issue will be closed and can’t be re-opened anymore
- When changing the status to IGNORE, the issue will be ignored for a defined amount of time (1 - 24 hours)
