Disk size recommendations for syslog server
 

Hello list.



We're about to set up a centralized syslog server, and were wondering if
there are any rules of thumbs regarding the size of the disk.

Disk size recommendations for syslog server
 

Well depends on the type of usage, but I guess 500 GB should be more than
sufficient.
Thanks!

Disk size recommendations for syslog server
 

Thanks for your reply.

500 GBs sounds quite a lot. We have around 200 servers, and they're usually
not producing too much logging (most of our applications have their own
logging, and doens't rely on syslog). I was hoping there maybe was some sort
of formula defining the avarage number of GBs logging pr server pr year, or
something like that.

Disk size recommendations for syslog server
 

Ken,
How many servers are you looking at logging? What syslog level?
What is your retention policy?

A basic rule of thumb would be to look at several of your
servers and see how large /var/log is just multiply it out by the number
of systems. Then add some slop-space for growth or unexpectedly high
activity.

Disk size recommendations for syslog server
 

We're planning on logging between 100 and 200 servers for now, but the
number will probably increase in the future. Haven't decided on a syslog
level, so we're up for suggestions.

About your calculation: I guess this is the most intuitive approach, and
seems like a good calculation. After a quick random sampling of our servers
indicates that the size of /var/log is between 15 and 30 MB. Most of these
logs are rotated, though.


Regards,
Kenneth
