Hi,
We would like to use squid snmp mibs to get statistics of squid
performance and cache gain.
We are using squid-3.1.10.By reference
ofhttp://wiki.squid-cache.org/Features/Snmp
We have a list of OIDs information in one line.Can we have any
document which provide more details regarding each OIDs. Some OIDs
are confusing.So if we have a document which provides more details
about them that is much helpful to understand them in appropriate
meaning.
There is no better documentation than that page. Unless you are one of
the rare people able to read MIB files without getting confused. In
which case the MIB.txt can be found in the Squid sources.
Some of are OIDs, which we decided to use with mrtg to get cache
gain, bandwidth saving statistics from squid.
*.1.3.2.1.2.0 cacheHttpHits Counter32 2.0+ Number of HTTP Hits
It provided url cache hit , my percaption is right?
Yes.
*.1.3.2.1.4.0 cacheHttpInKb Counter32 2.0+ Number of HTTP KB's received
It says that how many traffic comes from internet to squid , my
perception is right?
No. Received by Squid from clients.
*.1.3.2.1.5.0 cacheHttpOutKb Counter32 2.0+ Number of HTTP KB's
transmitted
It says that how many traffic goes out from squid to internet , my
perception is right?
No. Sent by Squid to clients.
*.1.3.2.1.13.0 cacheServerOutKb Counter32 2.0+ KB's of traffic sent
to servers
what does it says ?
"KB's of traffic sent to servers ". I think you already know what a
server is.
server means squid itself, right? internet to squid ( in traffic )
*.1.3.2.1.12.0 cacheServerInKb Counter32 2.0+ KB's of traffic
received from servers
what does it says ?
"traffic received from servers".
squid to internet ( out traffic )
if i m wrong, kindly correct me.
The server metrics do not mention HTTP because this is the KB used by
all server protocols.
Our network design :
internet
|
core router ----------> squid box
|
local network
We want to identify that how much cache gain / bandwidth saving we have
from squid?
Bandwidth Savings KB is: cacheHttpOutKb - cacheServerInKb
Bandwidth Savings % is: cacheRequestByteRatio.1
