Monitoring other stuff with MRTG
by Henrique Pantarotto 26 Jul '00

26 Jul '00

Hello Toaster friends, I am already monitoring my filers for these infos: - CPU utilization - NFS ops/seg - /vol/vol0 volume - ethernet traffic I was wondering if its possible to also monitor: - Cache age (as reported by sysstat command) - Disk kB/s read and write (also reported by sysstat) Any know know the SNMP OID to this? I tried searching at the MIB, but I couldn't find it. Thanks, _______________________________________________ Henrique Pantarotto SysOp Site São Paulo Terra Networks Brasil S/A A Internet mais sua do que nunca Tel: (11) 5505-5728 r.316/238 ICQ: 6934285 IT: henpa henrique(a)corp.terra.com.br

[Garrett Burke] For home directories (for a 160 user environment.) we use a default quota and then add specific user quotas for special cases. If user base changes then a default is the way to go We also use qtrees for all the stuff shared between users and these also have quotas on them. e.g etc/quota has entries like this /vol/vol0/releases tree 18G 250K joebloggs user@/vol/vol0/users 300M 10K * user@/vol/vol0/users 100M 5K > Thanks, > Ferdie ******************************************************************* This email and any files transmitted with it are confidential and are solely for the use of the individual or organisation to whom they are addressed.

Woah. I said Foundry can't do it (yet), but Alteon can. We have customers doing this already. Note that you need to make sure that your traffic is "symmetrical" - i.e., the returning traffic will definitely go through the same device - otherwise you'll have problems. You have to be *very* careful with this feature... > so right now theres no way to use my cache and maintain > the client ip throughout the connection? With Alteon you can - right now. With WCCP 2 you will be able to in the (near?) future. And Foundry will hopefully add the support soon too... [ As you probably know, NetCache adds an X-Forwarded-For header (if none already exists) to all requests it sees. This contains the client IP address. So web servers can get access to it that way if they want to... ] Cheers, Niall

I dont have a L4 switch > btw, i run WCCP from a CAT6000 with MSFC. I have attached some info I wrote up a few days describing IP spoofing. WCCP 2 is mentioned in here. To summarise, it should be possible with WCCP 2 but we haven't tested it or added the necessary support just yet. It'll be available "soon". Coding it should be straightfoward but there are other release issues to work on first...

Yeah, I've also heard the case presented by the faction that proposes Mibibyte, Mibibit, Kibibyte, Kibibit, etc. (sp for all those) to denote the 2^10^3n quantities. Seems quite reasonable to me.. except in the face of enormous socio-linguistic inertia I'm not sure I'd fight that hard. It's very nearly always been denary powers in raw disk sizes. I still think the binary powers are firmly ensconced in RAM, file sizes and bandwidth (MHz -> Mb and MB seems to pose less problem for people headers and preambles notwithstanding) in the mind of both the novice and the old-hand. More same-old same-old I think. I'll continue using whatever units my listeners/readers will understand most readily - anything else is poor communication. The issue that causes _me_ the most irritation is when people insist on using lowercase 'b' in Kb, Mb, etc. when they really mean 'byte' which, for me, and I suspect for many of us, would suggest 'bit'. Or when they're inconsistent. Sometimes it's not always possible to deduce from the context what they really mean, and, worse yet, they often don't see the issue as a problem! > Camiel Vanderhoeven wrote: > > > > Yes, the Ki, Mi, Gi etc. prefixes are a nice initiative to avoid > confusion. > > However, I have never seen anyone who seriously uses it.

Quotas for NT users

Question of the day: What is the best way to use quotas in an NT environment? My user list changes frequently, and my groups are a mess. Thanks, Ferdie

Binary numbering (off topic)
by Jay Orr 25 Jul '00

25 Jul '00

I had brought up the question a few months back of if 1GB is 1000KB or 1024KB. Now as everyone knows, historically 1024 Bytes is 1KB. Seems marketing has won the battle in terms of calling a "kilo" 1000 and not 2^10, at least with the government. I have been involved in a thread on comp.sys.sun.hardware about this topic and thought I'd share a posting about this. I'm hoping I'm not the only one unaware of this "new" standardization...

RE: Ndmp vs. Nfs backups.
by Kelly Wyatt 25 Jul '00

We use DLT7000, the compression devices on the netapp. Right now the master for these backups is a sun ultra 2. He really does not do much other than schedule jobs, perform database updates, etc. He has to create the list of files to backup and has to have a lot of temporary disk space and memory to handle this task. During the backups, most (all?) of the CPU cycles come from the filers -- all 760's. Here is some info on our sun: Sun Ultra 2 UPA/SBus (UltraSPARC-II 296MHz) with 384MB of memory. We have a 70GB raid array for /usr/openv to allow space for database growth. I thought he had more memory it may have been "borrowed" for an unexpected project. We do stagger our backups so that all backups jobs are not going for resources at one time. Each filer volume is a class for a lot of reasons. Originally we tried to limit our volumes to a size that can be restored within a 4 hour window... in reality, it is probably closer to 6 hours on some volumes, and we have a couple of "legacy" volumes from pre-multi volume days that are about 150GB. We have tested restores and seem to get around 15-17gb/hour restoring data, depending on the data.

Thanks for the data, it is quite useful! What kind of storage medium are you using (i.e. DLT?, AIT?) and what is your backup hardware (i.e. what are the specs of the system you use to run the backup software on)? This is the kind of info I can't even get the sales 'drioids to get for me... ----------- Jay Orr Systems Administrator Fujitsu Nexion Inc. St. Louis, MO
