I have squid-2.6.STABLE9-1 running on Fedora Core 6 stably and I am trying to use calamaris-2.59-1 for log analysis. While running calamaris, the following errors are generated in the log report: Invalid conversion in sprintf: "%t" at /usr/bin/calamaris line 3306, <> line 134591. Use of uninitialized value in sprintf at /usr/bin/calamaris line 3306, <> line 134591. Invalid conversion in sprintf: "%a" at /usr/bin/calamaris line 3306, <> line 134591. Use of uninitialized value in sprintf at /usr/bin/calamaris line 3306, <> line 134591. Invalid conversion in sprintf: "%;" at /usr/bin/calamaris line 3306, <> line 134591. Use of uninitialized value in sprintf at /usr/bin/calamaris line 3306, <> line 134591. Invalid conversion in sprintf: "%v" at /usr/bin/calamaris line 3306, <> line 134591. Use of uninitialized value in sprintf at /usr/bin/calamaris line 3306, <> line 134591. Line 134591 happened to be the last line in the log file. These errors are repeated a number of times and in addition the output report is full of large number (thousands) of blank lines and a few junk characters also. Surprisingly the log analysis is also carried out and a proper report is generated along with these errors. I have used the same version of calamaris on squid running on FC3 as well as CentOS 4.3 without any errors. What could be the reason behind these errors ? I have not selected any log format in squid.conf leaving the same at default setting none. Do I need to select any specific format ? Thanks, -- Manish Kathuria
