Log graphs are a useful set of data provided by Mettle SE. Mettle SE logs different sets of data about system and network performance and displays this data as graphs. To view log graphs go to: Monitoring >> Graphs.

Some graphs can be viewed in 'Inverse style' or 'Absolute style'. In the Inverse style the graph is split in the middle horizontally, incoming traffic is shown as going up and outgoing traffic is shown as going down. In the Absolute style graph is superimposed. Each graph is available in several time span and each of these is averaged over a different period of time based on how much time is being covered in each graph. Each graph will have a legend and summarisation of the data being shown.

There are six sub sections under Graphs they are- System, Traffic, Packets, Quality, Custom and Settings.

  • System graph: This shows a general overview of the system utilisation, including CPU usage, total throughput and firewall states.
  • Processor Graph: This shows the CPU usage for user and system processes, interrupts and the number of running processes.
  • Throughput Graph: Shows the incoming and outgoing traffic totalled up for all interfaces.
  • States Graph: Shows the system states but breaks down the value in several ways. It shows the filter states from firewall rules, NAT states from NAT rules. and the count of unique active source and destination IP addresses and the number of state changes per second.
  • Traffic Graphs: Shows the amount of bandwidth used on each available interface in bits per second. There is an 'Allgraphs' choice which will show all of the graphs in a single page.
  • Packet Graphs: This works like traffic graphs but instead of reporting based on bandwidth used it reports the number of packets per second (pps) passed.
  • Quality Graph: This graph tracks the quality of WAN interfaces with gateways specified. Response time from the gateway in milliseconds and percentage of lost packets is reported in this graph. Any loss on graph indicates connectivity issues or times of excessive bandwidth  use.
  • Custom: Here you can choose what graph you want to see. Choose from the list box the instance you want to be graphed, the graph style and the from and to dates.

Graph Settings:

Graphs can be customised to suit your preferences. Its possible to turn of RRD graphing is you prefer to use third party external graphing solution. Remember to click on 'Save' when you're finished.

  • Enable Graphing: Check the box to turn on RRD graphing. Uncheck the box to turn off.
  • Default Category: This option picks which tab to be displayed as default when you click Status --> RRD Graphs
  • Default Style: This option selects which style of graphs to be displayed by default, Inverse or Absolute.
  • Save settings when finished.
