[hobbit] Solaris vmstat and sar

But you should not see a major difference like 67% idle to 1% idle.... I've tried using two screens on the same system comparing sar to vmstat and using different intervals. vmstat significantly understates cpu usage in comparison to top, uptime, and sar. Does any have any ideas?

Vmstat shows the average use over the 5 second interval in you example below of vmstat 5 5. Sar shows the stats at the time the check was taken. So you are not comparing apples to apples. So they are going to give you different results.

I agree with you, but the snapshots that I emailed were taken at the same time. I'm now graphing both Sar CPU Utilization, and Hobbit CPU Utilization which uses vmstat. SAR shows the more correct CPU Utilization as compared to CPU Load (uptime). Also, "TOP" confirms that CPU is loaded. I have a multi-cpu version of top I use and all the CPU's are max'd with 1% or 2% idle. During this timeframe, cpu utilization using vmstat shows 67% idle.. I've seen this problem for a while now on multiple systems, but I just recently wrote my own sar script to put sar cpu into hobbit graphs to confirm this. Here's where I just did a 5 minute average in two different windows on the same box at the same time: vmstat shows 67% idle, sar, 26% idle: vmstat 300 2 kthr memory page disk faults cpu r b w swap free re mf pi po fr de sr s3 s3 s9 s1 in sy cs us sy id 0 4 0 68896560 24040168 673 3181 1548 15 14 0 0 12 12 0 0 12938 44125 19506 18 15 67 0 4 0 68896480 24040352 673 3181 1548 15 14 0 0 12 12 0 0 12942 44130 19525 18 15 67 $ sar 300 1 12:44:17 %usr %sys %wio %idle 12:49:17 31 32 11 26 TOP shows sar is correct: load averages: 18.56, 17.41, 17.71 12:54:14 866 processes: 836 sleeping, 1 running, 7 stopped, 22 on cpu CPU states: 14.6% idle, 36.6% user, 32.4% kernel, 16.5% iowait, 0.0% swap Memory: 48G real, 24G free, 18G swap in use, 65G swap free James _____ From: Lars Ebeling [mailto:lars.ebeling at leopg9.no-ip.org] Sent: Monday, December 03, 2007 12:28 PM To: hobbit at hswn.dk Subject: Re: [hobbit] Solaris vmstat and sar Hello, I don't think you should compare like that.

Sending alerts to remote system running qpage
by Keller_Liora＠emc.com 03 Dec '07

03 Dec '07

Hi, We are moving from BB to Hobbit. We are using qpage to send out pages from BB to a remote system which is running qpage. We would like to keep the qpage and modem on the same server, but the Hobbit server is running on a different system. Any idea how we can send alerts from Hobbit to a remote qpage server? Thanks, Liora

We are using qpage to page on cell phones, we don't use email-sms. On BB we configured "QPAGEARGS" and set the remote hostname.

Hobbit server doesn't start on CentOS 5 with hobbit-4.2.0-7.el5.re.i386.rpm installed
by spa＠syntec.co.uk 01 Dec '07

01 Dec '07

I installed an RPM of hobbit-4.2.0 called hobbit-4.2.0-7.el5.re.i386.rpm, which I probably got from here: http://rpm.razorsedge.org/centos-5/RE/repodata/repoview/hobbit-4-4.2.0-7.el5 .re.html It includes the All-in-one patch. So I configured the cfg files and started hobbit, but I get this in hobbitlaunch.log: 2007-11-29 17:33:47 hobbitlaunch starting 2007-11-29 17:33:47 Loading tasklist configuration from /usr/libexec/hobbit/server/etc/hobbitlaunch.cfg 2007-11-29 17:33:47 Loading hostnames 2007-11-29 17:33:47 Loading saved state 2007-11-29 17:33:47 Cannot access checkpoint file /usr/libexec/hobbit/server/tmp/hobbitd.chk for restore 2007-11-29 17:33:47 Setting up network listener on 0.0.0.0:1984 2007-11-29 17:33:47 Setting up signal handlers 2007-11-29 17:33:47 Setting up hobbitd channels 2007-11-29 17:33:47 Could not get shm of size 262144: No space left on device 2007-11-29 17:33:47 Cannot setup status channel 2007-11-29 17:33:47 Task hobbitd terminated, status 1 This is the first time I've started it, so I presume that this is normal: "Cannot access checkpoint file /usr/libexec/hobbit/server/tmp/hobbitd.chk for restore". The problem looks like this: "Could not get shm of size 262144: No space left on device". I see that there are two similar issues listed on http://www.hswn.dk/hobbit/help/known-issues.html that relate to FreeBSD, but none of the sysctl keys listed are in this version of Linux: # cat /proc/version Linux version 2.6.18-8.1.15.el5.centos.plus (mockbuild at builder6.centos.org) (gcc version 4.1.1 20070105 (Red Hat 4.1.1-52)) #1 SMP Thu Oct 25 06:49:40 EDT 2007 Google returns 1 result for "Could not get shm of size" "No space left on device" and that was the Known Issues page I've already checked. Any ideas? Also, I noticed that the hobbitd.pid file did not get deleted when hobbitd terminated. It seems like it should have been. Many thanks, Sebastian

Monitoring HP StorageWorks EVA disk array

I checked Deadcat.net and didn't find anything. Does anyone have a script to monitor a HP StorageWorks EVA disk array with Hobbit? Just checking before I start working on it myself. Thanks. -- Robert Herron robert.herron at gmail.com

security hole? server masquerade
by yf.liang＠yahoo.ca 30 Nov '07

30 Nov '07

We have 2 servers: 1.2.3.4 servera 4.5.6.8 serverb During DR(discovery test), we changed the local name of serverb to servera, to perform test to see that servera applications have been recovered. So, externally both return pings to their original name. However, when logging into serverb, the uname -a returns servera. The change was done by changing /etc/hosts and uname. 4.5.6.8 serverb servera When the hobbit client is running on serverb, all processes have servera in them. Hobbit server starts to report serverb status as servera !! Doesn't the hobbit server check that the ip of the reporting server (serverb) and reject it, since it does not match the ip address of servera? --------------------------------- Be smarter than spam.

CPU Utilization, Not Good
by jkwade＠futurefrontiers.com 30 Nov '07

30 Nov '07

Hi, I've asked this several times, but I really have not received a good answer. Hobbit doesn't really seem to monitor cpu utilization correctly. For example, I can look at the load, login to the box, and then run top. Top shows that cpu utilization is at 100%, 0% idle time. However, the "trends" utilization graph shows 20% cpu utilization. Can someone tell me why? Thanks..James James Wade
