You can use the tool called amp-plotconvergence to help you examine the output of an Amp log file. Run amp-plotconvergence -h for help at the command line.
You can also access this tool as plot_convergence from the amp.analysis module.
There are several other plotting tools within this module, including plot_parity for making parity plots, plot_error for making error plots, and plot_sensitivity for examining the sensitivity of the model output to the model parameters. These modules should produce plots like below; in the order parity, error, and sensitivity from left to right. See the module autodocumentation for details.
