Elvis SAS Log Analyzer

version 3.0, 2023-10-16 Download

Elvis is a Windows app for working with SAS logs. Open any SAS .log file in Elvis and you'll be able to navigate around it and search it far more easily than using a non-specialized plain text editor. If there are any ERRORs or WARNINGs, Elvis will take you straight there so you can start debugging right away.

Elvis also works with logs produced by the World Programming System (WPS).

Features include:

  • the new Log Explorer which gives you an easy-to-view and easy-to-search overview of key events in the log - data sets read and written, macro variables set and resolved, librefs declared, and more.
  • the Folder View which immediately shows you the status - contains ERRORs, contains WARNINGs, or CLEAR - of any other logs in the same folder.
  • the Call Tree which displays all macro calls in the log, and their hierarchical relationship to each other.
  • the Quick Find pane which gives instant access to ERRORs, WARNINGs, "special" lines and highlighted lines.
  • the Highlighting dialog which allows multiple search terms to be highlighted, and searched for, throughout the log.
  • colour-coding of each line according to its type (MPRINT, MLOGIC, SYMBOLGEN etc).
  • jump straight to the first error (if there is one) when a log is loaded.
  • quick and simple hiding of certain line types, entire macro calls, or even all calls to a certain macro.
  • the ability to define a "special" line type, recognised by your own application-defined prefix (eg "SPECIAL: This is a custom note.").
  • Views, which allow you to save commonly-used combinations of options and quickly restore them.
  • Reports, summarising important log information: recover runnable SAS source from MPRINT lines, summarise all called macros, and more.
Log Explorer

The innovative new Log Explorer feature goes well beyond simply showing a colour-coded view of your SAS log. It presents all the key events in the log to create a searchable summary, showing librefs created and cleared, data sets read and written, macro variables set and resolved, and much more. This lets you understand the log much faster - if a data set is being created with fewer observations that it should, you can easily find the steps that contributed to that data set and see where the data was read from, what WHERE clauses were applied at each stage, and so much more.
Folder View

Shows all the logs in one or more folders and gives an instant, up-to-date indication of each log's status - red if there are errors, green if it's clean, and so on. This is a great way to monitor a large set of SAS programs and see instantly if any of them have any outstanding issues.
Date Calculator

An intuitive, graphical way to convert between numeric SAS date values and real dates, and to calculate date ranges.

This version of Elvis includes telemetry that records certain details of how you use it and uploads this information to our servers on a roughly weekly schedule. This is an important part of the software development process as it helps us to understand how Elvis is used, the types of computer that it's used on, the typical size of the logs it's used with, etc. We guarantee that:

  • no personal data is collected;
  • no data from your logs is collected other than some basic metadata such as the size, number of lines, etc;
  • log filenames are not collected;
  • all collected data will be kept strictly confidential within Oceanview Consultancy and will not be shared with any third party.

The usage log file is stored in <user folder>\AppData\Local\Oceanview Consultancy\Elvis and you can view this at any time if you'd like to see what data is being collected.

Telemetry is automatically enabled when Elvis is installed but you can change this at any time using the Preferences dialog.
