Ticket 03 – Determine Last Application Outage

Title: “When was the last outage for this new web server?”

Ticket Description

The team is evaluating a newer version of the web server running on node 10.1.20.201. This node is a member of the web_servers_pool pool on WestRegion-bigip-01.

Before moving forward with broader deployment, the team wants to understand the stability of this node.

How long has it been since this application experienced an outage?

Context

Device Name: WestRegion-bigip-01

Pool Name: web_servers_pool

Pool Member: 10.1.20.201:80

Tasks

Navigate to:

Dashboards >> BIG-IP Device >> Device Pools

From the Device dropdown, select:

WestRegion-bigip-01

From the Pool dropdown, select:

web_servers_pool

Locate the panel:

Pool Member Request Rate

Click the “Expand panel” button on top right of that panel

Use the Time Range dropdown in the upper-right corner of the dashboard to review historical availability data.

Try adjusting the range to broader views such as:

• Last 1 hour (focus on this)
• Last 24 hours
• Last 7 Days
• Last 30 Days

Identify:

• Does the pool member request have any anomalies?
• Does there appear to be any one pool member taking more requests than another?
• In the graph key, de-select all members EXCEPT member 10.1.20.201:80

Deliverables

Briefly answer the following focusing on 10.1.20.201:80:

• What is the highest req p/s that you’ve observed?

Review the following for additional information and trends (navigate back to summary page):

• Observe date and time of the last outage (if any)
• Approximate duration of the outage
• Time elapsed since the outage
• Any observations about stability trends

Hints

• Hover over points in graph to see event day and time
• Try expanding the time range (Last 24 Hours, 7 Days, 30 Days).
• Look for state transitions from isAvailable to unavailable.
• Zoom in on the graph if necessary to see shorter outages.

This concludes Ticket 3.
