Metrics Database
The system and network performance metrics database is a third party application that provides you with means to create a variety of graphs out of collected monitoring data.
The following is an example for the graphical presentation of PM data collected on network elements in a managed FOX61x network:
Proceed as follows:
1 Set up a PM data collection job from the NEM Desktop - Network - Performance Management as described in Create PM Collection Job. In this example, we select core unit front ports of at least one core unit in at least one FOX61x.
2 Once the job is activated and has collected the first PM data from the network, open the Metrics Database and select the “Explore” tab on the left hand side of the UI.
3 In the Data Explorer, choose the type of graphics you need. The default type is “Graph”; you can select any available type like band, gauge, graph (default), graph + single stat, heatmap, histogram, mosaic, scatter, single stat, table. In this example we select the default, i.e. graph.
4 In the pad at the bottom, titled “FROM”, select the “NMS” bucket. This will add a new “Filter: _measurement” pad.
5 In the “Filter: _measurement” pad, make sure “measurement” tag is selected. below the measurement tag, select (set a tick in the box) any measurement you want to include, e.g. “ethernet_counters”, “rmon_eth_stat”, or rx_tx_counters”, etc. In this example we select the “rmon_eth_stat” measurement. Upon selecting the filter option, a new pad “Filter: _field” is opened.
6 In the “Filter: _field” pad, select any tags presented, e.g. the six tags pkt_64, pkt_125, pkt_255, pkt 511, pkt_1023, pkt_1517.
7 In the next pad “Filter: card_model” select the core unit name(s).
8 In the next pad “Filter: card_name” select the core unit name(s) and slot(s). You may go on with selecting filtering options until there are no further options left. We stop here to see the results:
9 To create a graphical presentation of the data, click the “Submit” button. This will add the graphical view of the data collected up to now for the time range selected (e.g. “Past 3h”) above the filter pads.
10 To save this graph for later use, click the “Save As” button in the upper right area. This will open a “Save as” options window.
11 Select an existing Target Dashboard (if existing), or create a new one (“Create a New Dashboard”). We create a new one, named “Network PM”. Give the new cell a name, e.g. “Packet Statistics”.
12 When done, click “Save as Dashboard Cell”. This will change the view to “Boards” tab and add the “Packet Statistics” cell to that view.
13 You can rearrange, resize or move cells by clicking on the upper left or lower right corner of the cell.
