availability report and backtracked archives

[drookie]

Hi.

I'm running nagios for several years. I definitely have the archives for past year, but no matter what I'm doing nagios shows the reliability report only for last 65-69 days. Is there any way to get more data from past ? I tried to manually set the number of backtracked archives to 99 (for some reason this field is only 2-digit long), but nagios drops it to 60 all the time.

P.S. Nagios 3.4.1.

Thanks.

By default "the archives" are simply the rotated logfiles. Are you using logrotate or anything to prune old logfiles.

There is no setting I'm aware of in Nagios that will purge older files so I'm not sure what you mean when you say

I don't. There's plenty of old logfiles in the archive directory:

And, what's more important - this is the same directory where the logfiles for these 60-65 days are kept.

I'm referring to this (above the update button):

[tgriep]

If you run that report for all of last year, it comes up empty?

[drookie]

Nope, it's not empty, but it's only 67 days long. I do have more archives than for 67 days, and I'm pretty sure I didn't change the name of the service during long time.

For example:

[tgriep]

Kind of looks like either corrupt or missing data.
Do you get the same 67 day result if you run the report from January 1st 2015 to today?

[drookie]

No, I get longer report - 79 days, first date row is for December 28th.

If this is some kind of data corruption - is there any way to understand where it occured and what exactly become corrupted ?

[jdalrymple]

Do you have data from any days between 1/1/2014 and 10/25/2014? If so, could you pick any of those days grab a few lines from one of them and post it?
