In cases of the graphs on numeric metrics are not enough, the functional Maths on graphs can be used. For instance, it can be used for plotting a graph of:
- the total CPU load of several hosts, e.g. the main and the backup;
- the ratio of successful transactions to their total number;
- the revenue difference in two stores;
Creating a graph based on mathematical operations is similar to adding a new graph. It is sufficient to select the necessary metrics from the list, use mathematical operations, braces and constants.
