Re: [squid-users] normal squid , can we cahce fcebook vidoes ?

[FredT]

Eliezer,
I'm not sure it's due to the Etag only...
I did many tests and some with Etag are cached and some are not.
But it seems objects including a "Transfer-Encoding: chunked" cannot be
cached with a Etag. I don't know if it's related or not, maybe you know 

Bye Fred

Re: [squid-users] AUFS vs. DISKS

[FredT]

Fred,
We now have the 3.5.8 deployed with our clients, not yet switched to the
3.5.9...
"strange" messages are not a problem because i suspect it's generated by the
cache_swap_low/high, cleaning old objects.
I suppose the Squid cleans old objects but another squid process does not
take care this cleaning and see the (deleted) object does not exist anymore
so it alerts there is something wrong...
Personaly i do not take care these warning messages from the cache.log as
squid is smart enough to manage missing objects.

Based on previous answers, diskd is for freebsd with 1 process only, when
the ufs/aufs are with many processes.
Also, as you said, it seems the diskd process was modified with the latest
builds...

bye Fred

Hi Fred,
you cannot expect a higher % saving without using a storeid tool.
20% saved band is already good with a simple squid...

Re: [squid-users] Bug in the squid snmp

[FredT]

Amos,

Ok, i can understand that definition but why does squid display a wrong
number ? in the concept that is the question !
If you must respect a Gauge32 type, just display the value in KB or MB or TB
but display the right value, see what I mean ?
Or add a new snmp line to indicate the units or fix the value with MB unit,
but you cannot leave this with a wrong value, it does not make sense...

Re: [squid-users] Bug in the squid snmp

[FredT]

Hi Amos,

So what ?
I noticed it's a  32 bit integer   
with a "4,294,967,295" limit in unsigned but it cannot be an excuse to
provide a wrong number...
The squidclient displays the right value but as the same value from the snmp
is an unsigned so here it's allowed to truncate the value ? does not make
sense...

What's the right way: respect the unsigned int limit or display the right
value ?
From my side I suppose the right way is to display the right value, so I
think you should fix the snmp with the right types to provide the reality 

Does it make sense for you too ?

Bye Fred

[squid-users] Bug in the squid snmp

[FredT]

Hi the Squid team,

It seems there is a bug in the snmp engine regarding the "Storage Swap
size", it returns a 4 billion integer maxi:
SNMPv2-SMI::enterprises.3495.1.3.2.1.14.0 = Gauge32: *4101140992*-> 4.1TB

http://wiki.squid-cache.org/Features/Snmp:
*.1.3.2.1.14.0   cacheCurrentSwapSize   Gauge32   2.0+   Storage Swap size


Same with the squidclient command:
Disk hits as % of hit requests: 5min: 59.9%, 60min: 59.9%
*Storage Swap size:  12690678368 KB* -> 12.6TB
Storage Swap capacity:  90.1% used,  9.9% free
Storage Mem size:   8307652 KB
Storage Mem capacity:   99.0% used,  1.0% free
Mean Object Size:   290.57 KB

Am I right or am I wrong ?

Bye Fred

Hi Fred,
By keeping objects 30 days maxi, does it mean you expect to upgrade all
windowsupdate objects in 30 days ?

I'm still thinking we should have an option forcing some type of objects
that could never be deleted... ;o)

Re: [squid-users] Squid 3.5.7, cache_swap_high, bug or not bug ?

Hi Amos,
I see the new build squid-3.5.7-20150829-r13899 released taking care the
cache_swap_high, does this build apply the limit with the "Filemap bits in
use" or is it on the cache "Percent Used" only ?

Re: [squid-users] Squid 3.5.7, cache_swap_high, bug or not bug ?

[FredT]

Hi Amos,
We have applied the patch with the client on the squid in prod a coule of
hours ago...
We can see now a real aggressive objects cleaning 

I can confirm a 200 obj/sec is a minimal number with huge traffic, you could
fix the value a bit higher (250-300) that would be perfect.

Let's see this patch in the next official build... 

Bye Fred

Re: [squid-users] Squid 3.5.7, cache_swap_high, bug or not bug ?

[FredT]

Hi Amos,

OK, clear :o)

Did you think to apply the low/high to the "Filemap Used" too ?
From my point of view the Filemap Used is much more important in the objects
cleaning because it reaches the 16 million entries faster than the cache
space, especialy with small objects (<64kb).

Re: [squid-users] Squid 3.5.7, cache_swap_high, bug or not bug ?

[FredT]

Amos,

Uploading the patched squid took time to be agreed by the client, sorry but
the server is in production and we cannot take the risk to see if the action
will crash or not the squid, i don't want to lose this client...

If you fix in the next release the cache_swap_low/high taking care the
Percent Used and the Filemap, it would be a good solution at the moment 

Keep us posted...

Bye Fred

Re: [squid-users] Squid 3.5.7, cache_swap_high, bug or not bug ?

[FredT]

Hi Amos,
Since the patch, the Percent Used is decreasing correctly, no new 100% at
the moment.

Why not using the Req/min as the value to use in the cleaning when the
cache_swap_low/high are reached ?
ex: Average HTTP requests per minute since start:   19232.8
Btw, when the cache_swap_low is reached, the squid could use 25% of the
req/min for the cleaning and with the cache_swap_high the squid could use
100%.
This is an example, there are tons of data in the squid we could use 

Or, we could have special options to define by ourselves the number of
objects to clean, example:
- cache_swap_low_del_object 256
- cache_swap_high_del_object 1024

Bye Fred
