Uptime Report Tool

The IRIS DMC has developed a web tool for internal use and for use by data providers that generates a report which can serve as information on archived data and as a metric and diagnostic of archive processes. Uptime reports were originally developed as an automated reporting mechanism for the US Array project and proved useful enough to be further developed for this wider use.

The uptime report tool generates an ASCII report and xls attachment of archived data percentages which are emailed back to the web tool user. The generated report has links to mda and goat which allow for further exploration of problems that are revealed by the report.

The percentages are based on channel uptimes as defined by meta data in the DMC’s database compared to channel data that has successfully been archived at the DMC. The percentages can help proof:

  1. Processes that get data to the DMC
  2. Processes that archive data received at the DMC
  3. Channel uptime meta data

The figure below shows the form that drives the uptime report generation. A report can take hours to generate and form users are encouraged to reduce their wait time by selecting or rejecting channels via the regexp fields in the form to produce a report of only relevant channels. A report may be done by network or virtual network and is limited to a 5 year time range.
