problem with rotatelogs time of day formatting

I'm trying to set up piped access and error logs, with "rotatelogs", as 
I'm porting the configuration from Solaris box to a small cluster of 
Linux VMs running RHEL 5.

We're trying to use file name patterns like:

error_log_chnuinfow3.%Y-%m-%d-%H_%M_%S.txt

The date substitutions are working, but the time of day characters come 
out as zeros. An example, and some system information, are quoted below.

I originally was trying to use rotatelogs from the Red Hat httpd RPMs.

But since they are a version of httpd 2.2.3 with back-ported patches,
I then tried building the newest httpd 2.2.21 from source, off to one 
side, with static support binaries.

That's the source of /usr/local/sbin/rotatelogs below. But both versions 
seem to have the same symptom.

I wrote a C program to test the system strftime, and that seemed to work 
as expected, but I suppose the APR library date/time library is what is 
being used, making that somewhat moot.

(I'm also aware of logrotate, and the legacy server just stops and 
starts the server in a nightly job that also rotates the logs in a shell 
script. Others wanted to do use piped log rotation,
I'm trying to make it work.)

Any ideas?

mod_include.so: undefined symbol: ap_escape_html2 Error

After a system upgrade, I'm unable to start the Apache server anymore.
Using the following command to start Apache server 'httpd -f /opt/csvn/data/conf/httpd.conf -k start' , I got the following error:
httpd: Syntax error on line 20 of /opt/csvn/data/conf/httpd.conf: Cannot load /opt/csvn/lib/modules/mod_include.so into server: /opt/csvn/lib/modules/mod_include.so: undefined symbol: ap_escape_html2
 
I'm not sure what to do with the undefined symbol: ap_escape_html2
 
Running on FC5 and httpd-2.2.0-5.1.2.
 
Thanks in advance.  Any help is appreciated.

The function was included in Apache 2.2.12. It is used by mod_include
and provided by the Apache core (the httpd binary). So it seems you
updated the module, but not the httpd binary itself.

The timestamp used for the file names is always the previous point in
time where rotation would have happended. You configured a daily
rotation pattern (86400 seconds). By default it rotates at midnight in
GMT timeone, or using the local timezone if rotatelogs is used with the
flag "-l".

So I guess either your system runs on GMT, or you used "-l". With 86400
rotation always happens at midnight (GMT or localtimewith -l) and the
time 00:00:00 is correct. Note that even the new files created when you
start Apache will have the formatted timestamp for the "previous point
in time where rotation would have happended", so when using 86400 it
would be last midnight (relative to GMT or localtimewhen using -l).

Try using a very different interval, like e.g. "90" and observe, whether
the files rotate every 90 seconds and now produce more interesting
formatted timestamps.

Regards,

Rainer

Re: problem with rotatelogs time of day formatting

When you rotate on time interval, rotatelogs names the file not after the time it logged the first msg but from a normalized start of an interval. 24 hour intervals start at midnight

httpd Will Not Start ....

I'm confused.
I issued the following command to start httpd, but no error and informational message displayed.  Of course, there is no httpd process.
 
'/opt/csvn/bin/httpd -f /opt/csvn/data/conf/httpd.conf -k start'
 
When I looked at the error log file, the only thing that I saw was a warning message.
 
[Sat Oct 01 06:19:05 2011] [warn] Init: Session Cache is not configured [hint: SSLSessionCache]

Does anyone knows what is going on?  What can I do to investigate this problem?
 
Thanks for any help.

OT maybe ... but what is lmgtfy.com - seems to be a cloaked proxy via 
godaddy to google cookies.

No, it's a polite way to send asker to flipping google the question.
