PALNI System Uptime Statistics for 2007

Fri, 04 Jan 2008 14:25:47 -0500

News Article:

PALNI staff use system monitoring software to monitor and automatically log whether our Ex Libris Aleph system is online and operational at 15-minute intervals throughout the day. If the PALNI system is down for any reason, an "on-call" member of the PALNI staff is automatically paged so that any problem can be resolved quickly.

We have completed a review of our system monitor system log file for the 2007 calendar year. It shows that we experienced a total of 8.5 hours of unplanned Aleph system downtime during 2007. In addition, we scheduled a total of 9.25 hours of planned downtime over the 12 months for Aleph Service Pack installations and for other routine planned system maintenance activities.

As the Aleph downtime table shows, staff kept the PALNI system online and operational for over 99.9% of the approximately 8600 scheduled hours of PALNI system operation during the 2007 calendar! That is a significant achievement for a complex system like PALNI's that is routinely kept online on virtually a 24 hrs x 7 days per week basis.

PALNI WebOpac Testing Statistics

Mon, 22 May 2006 11:17:11 -0400

News Article:

On Thursday, May 4, 2006, some of the PALNI staff, armed with stopwatches, fanned out to PALNI sites in the area to test response time of the WebOpac. Staff traveled to DePauw, Butler and UIndy to do the testing. Three others tested response time on keyword searches from the PALNI offices. The testers used a sample script of 96 actual user searches pulled from web server log files and each person was assigned a different starting point to avoid caching issues. The searches were conducted between 1:30 pm and 3:30 pm, when the system is most active.

The tests did not reveal any major surprises. They do confirm, however, that some PALNI libraries are experiencing real OPAC response time problems. In addition, the results suggest that

Except for sorting, keyword search response times do not seem to be related in any direct way to the number of hits,
Searching the PALNI union catalog is faster than searching any individual library catalog,
PC problems can contribute to significantly slower response times,
Keyword search response times can vary significantly from one library to another.

Attached is a small chart that shows, for each library, the number of searches that retrieved more than 250 records and did not require sorting, the average search time, the median search time, and the number of searches that took more than 3 seconds. Also attached is a spreadsheet of all of the search terms and the results of the searches.
