Tim, can u take a look? We have this file to enable nagios monitoring for gluster. We can't make it as a sample since our monitoring solution requires data collection in every minute. We have see similar issues in the past as well where this command fails exactly at 00:00:01 +0000 (UTC). Here also the same case, it failed at "Date: Sun, 21 Feb 2016 00:00:01 +0000 (UTC)". Darshan can u investigate further? (In reply to Ramesh N from comment #3) > We have this file to enable nagios monitoring for gluster.

Ramesh, As you mentioned, we had the problem of an entry not being made into sysstat's saDD file during day's transition (at 00:00:00 hrs). We fixed it by adding another entry in same cron job for making an entry to the file at last minute of the day. with this that issue was solved. But the issue here seems to be resource un availability. the cron job /etc/cron.d/sysstat tries to collect and update the sysstat data every 10 minutes once and our cron job does the same thing every minute once. and while updating the sysstat data file(var/log/sa/saDD) a lock on the file is held by entity updating it. If multiple jobs try to update simultaneously only one will succeed. We should check if this issue arises if we have only one cron job running to update sysstat data. Can you check if this exists with gluster-systat crontab alone? Is there a supported work-around for this issue? Hello, is there any update on this issue ? Thank you for your report. However, this bug is being closed as it's logged against gluster-nagios monitoring for which no further new development is being undertaken. What is the suggested workaround for parallel executions of /usr/lib64/sa1 from cron? # egrep -r '\<sa\>' /etc/cron.* /etc/cron.d/gluster-sysstat.crontab:59 23 * * * root /usr/lib64/sa/sa1 60 2 /etc/cron.d/gluster-sysstat.crontab:*/1 * * * * root /usr/lib64/sa/sa1 1 1 /etc/cron.d/sysstat:*/10 * * * * root /usr/lib64/sa/sa1 1 1 /etc/cron.d/sysstat:# 0 * * * * root /usr/lib64/sa/sa1 600 6 & /etc/cron.d/sysstat:53 23 * * * root /usr/lib64/sa/sa2 -A |
