I had the same problem when I moved from PCM to IMC. I can get you working on the bandwidth monitoring, but you won't have the ability to see who is using the bandwidth without getting NTA. PCM had the ability to show you who the top talkers were on a per-minute basis, which was great when trying to figure out who was using the bandwidth on a small pipe, such as a single T1. NTA kicks the snot out of PCM when it comes to traffic analysis and reporting, you may want to buy it if you need that kind of info.
OK, how to get it so you can see your bandwidth utilization:
1. setup performance monitoring
- click Resource - Performance Mangement - Performance View
- Click Add - Trend Line
- Select "System - Interface Statistics"
- Click Add next to Interface Receiving rate (bps) and Transmitting rate (bps)
- Click the "Interface" button
- Click Device View - Switches
- click a switch that has a port you want to monitor
- Click the port and click the down arrow to add it to the selected interfaces box
- you can click on the Device List tab to select another switch and add more ports/interfaces
- when done, click OK, Next, Save
- Give it a name and description (ie: Name: T1 locations. Description: All sites with a single T1)
- Click OK, Close
2. Set Alert threshold
- If you group interfaces that have the same utilization thresholds, such as all sites with singe T1s, you can then click the "gear" setting to the right of the monitoring instance in the performance view screen.
- Click Modify Threshold
- Uncheck the Global Index Settings option
- select the Receive Rate and set it to what you want your threshold to be. Here is what I do for my T1 sites:
- Threshold 1 value = 1.2 Repeat Times = 15 Alarm level = Minor
- Threshold 2 value = 1.3 Repeat Times = 20 Alarm level = Major
- Interval = 60
Note: I set IMC to only alert on Major alarms and above
What this does is tells IMC to alert me when my T1 hits 1.3mbps 20 minutes in a row
Now that you have the monitoring setup, let it run for 30 minutes to collect some data
3. Monitor your traffic
Note: you can view traffic a couple different ways. I suggest setting up the Tiling method, but will explain both
3A - Monitoring on demand
- Click Resource - Performance Mangement - Performance View
- you should see the monitor you setup earlier. click on it and it will bring up the trend graphs you defined and show the thresholds you defined too
- you can adjust the amount of data shown by clicking the links at the top of the page
3B. Monitoring using Tiling
- point your mouse at the gold Star - Display Tiling - Configuration
- Click and drag the Performance Trend button into the screen area with the grids
- stretch the box to fit on the screen
- right click - parameter configuration
- add instance
- scroll down and select System Interface Statistics
- expand the switch(es) and select the ports you setup during the monitoring phase - do this for Interface receive rate and transmit rate (bps) - OK when done. OK..
- click the SAVE icon!
- close the configuration screen
- go back to the Gold Arrow - Display Tiling - Select the view you just setup.
Note: the display tiling is meant for monitoring on a screen in a network operations center. We have 4 monitors going, each with multiple windows on it. As you add more monitoring (maybe you have sites with 2 T1s, you could setup a new monitoring instance for those ports), you can add more performance trends to the screen and tile them to fit next to each other on a screen.
I'll leave this alone for now. give this a try. post a reply and I will check back to see if I forgot a step and left you in the lurch.
