I admit I've only breezed through the code and now I'm looking for a cheat sheet on how to use the hobbitd_locator. Thanks Gregory R Shea EMC Corporation

Solaris Zones
by jkwade＠futurefrontiers.com 28 Oct '09

28 Oct '09

Hello, I sent an earlier email asking if anyone had written anything for Solaris Zones so that it sends xymon information about the zone, instead of the global zone. I have zonestat loaded on, and it give information on the trends section. I received no answers, so I've started writing one myself. I have some questions that I was hopping someone might be able to help with, so I can make the test easier. What I'd like to do is have my test send status in the same format as xymon does for a client. For example, memory, physical and swap, along with CPU load. Is there a way to accomplish this? Thanks.James

Apparently, last night our Exchange server stopped receiving email until it was rebooted this morning. Everyone is up in arms. Hobbit showed nothing unusual. Does anyone have any way to monitor Exchange? Eric Jacobs Infrastructure and Operations Information Technology Group Phone:215-682-5354 Email:ejacobs at thomaspublishing.com

Dual BBDISPLAY lines
by d.tom.schmitt＠L-3com.com 27 Oct '09

27 Oct '09

I am working on the BBWin XML configuration file. Server is running Xymon 4.3.0-0.beta2 I added these two lines to the beginning of the configs after the comments: <setting name="bbdisplay" value="128.170.1.151" /> or monitor1.csw.l-3com.com <setting name="bbdisplay" value="128.170.1.161" /> or monitor2.csw.l-3com.com Only the first Xymon gets the updates, the second just looks like it is doing the standard connectivity icons. The name in both of the bb-hosts entries are identical. MONITOR1: bb-hosts entry: 128.170.1.150 dschmitt.csw.l-3com.com # conn BBDISPLAY: MONITOR2: bb-hosts entry: 128.170.1.150 dschmitt.csw.l-3com.com # conn BBDISPLAY: I have restarted the service and monitor2 xymon. Thanks, Tom Schmitt Senior IT Staff - R&D

[hobbit] performance help needed

hi all, do you have a lot of memory ? If yes you can create tmpfs for your rrd and sync the tmpfs every couple hours. We do it for a little hobbit server with 3500+ devices. For rrd hist and www dir.

I bounced around the idea of external storage, but even here at EMC there is a cost associated with external storage, that's why I tried the second drive. I've read about the enhancements in 4.3, but thought I should upgrade from RH 4.7 to RH 5.3 first (RH is the official supported Linux) as there were IO improvements in the kernel. I also tried a newer version of RRD 1.2.30 and 1.3.8. RRD 1.3.8 doesn't work Hobbit 4.2. On to the storage requisition process.... Thanks -Grs- Gregory R Shea EMC Corporation

performance help needed
by shea_greg＠emc.com 27 Oct '09

Hi all, First off, sorry for the long post, I'm trying to supply as much data as possible for analysis. I have a single Hobbit server with approximately 3500 hosts, a mixture of windows and unix, some DB tests, some BEA tests and a few custom tests. I have over 70000 RRD files which seems to be causing Hobbit performance problems, most specifcally clock offset. I have a cron job that restarts Hobbit every 30 minutes otherwise the offset grows so large it eats all memory and OOM kill starts. NTP is fine, it seems to be the time it takes for Hobbit to process the client data. OS resides on RAID1 146GB drives SAS 15K RPM, second drive for RRDs is a single 300GB SAS 15K RPM. At the end is a graph showing the clock offset. What else can I try? I moved the RRDs off to a separate drive hoping this would help, but the write per second is high. I've tried reducing read-ahead, mounting noatime,nodiratime, changing IO scheduling to deadline, nothing seems to help. Here's a sample output from iostat -xd 60 10: Device: rrqm/s wrqm/s r/s w/s rsec/s wsec/s rkB/s wkB/s avgrq-sz avgqu-sz await svctm %util sda 0.00 68.08 0.17 20.02 1.33 704.78 0.67 352.39 34.98 4.25 210.36 3.47 7.01 sda1 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 sda2 0.00 68.08 0.17 20.02 1.33 704.78 0.67 352.39 34.98 4.25 210.36 3.47 7.01 sdb 0.00 674.60 1.53 311.04 12.27 7887.05 6.13 3943.52 25.27 24.50 78.38 1.91 59.70 sdb1 0.00 674.60 1.53 311.04 12.27 7887.05 6.13 3943.52 25.27 24.50 78.38 1.91 59.70 sdb2 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 dm-0 0.00 0.00 0.17 88.10 1.33 704.78 0.67 352.39 8.00 20.31 230.09 0.79 7.01 dm-1 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 Drive sdb1 is housing the RRD files Memory seems fine: Memory Used Total Percentage Physical 7645M 7973M 95% Actual 4688M 7973M 58% Swap 64M 9983M 0% [hobbit at hobbitmon rrd]$ uname -a Linux hobbitmon 2.6.9-78.0.8.ELsmp #1 SMP Wed Nov 5 07:14:58 EST 2008 x86_64 x86_64 x86_64 GNU/Linux [hobbit at hobbitmon rrd]$ cat /etc/redhat-release Red Hat Enterprise Linux AS release 4 (Nahant Update 7) Output from bbgen: bbgen for Hobbit version 4.2.0 Statistics: Hosts : 3506 Status messages : 41934 Purple messages : 0 Pages : 171 Output from bbtest: bbtest-net version 4.2.0 SSL library : OpenSSL 0.9.7a Feb 19 2003 LDAP library: OpenLDAP 20213 Statistics: Hosts total : 3511 Hosts with no tests : 2390 Total test count : 1470 Status messages : 1596 Alert status msgs : 0 Transmissions : 18 DNS statistics: # hostnames resolved : 358 # succesful : 339 # failed : 19 # calls to dnsresolve : 530 TCP test statistics: # TCP tests total : 411 # HTTP tests : 161 # Simple TCP tests : 250 # Connection attempts : 411 # bytes written : 24722 # bytes read : 543706 TIME SPENT Event Starttime Duration bbtest-net startup 1256584823.382254 - Service definitions loaded 1256584823.383506 0.001252 Tests loaded 1256584823.468743 0.085237 DNS lookups completed 1256584828.565010 5.096267 Test engine setup completed 1256584828.572444 0.007434 TCP tests completed 1256584839.000192 10.427748 PING test completed (1082 hosts) 1256584881.612835 42.612643 PING test results sent 1256584890.617168 9.004333 Test result collection completed 1256584890.617453 0.000285 LDAP test engine setup completed 1256584890.617453 0.000000 LDAP tests executed 1256584890.617454 0.000001 LDAP tests result collection completed 1256584890.617455 0.000001 NTP tests executed 1256584894.477007 3.859552 RPC tests executed 1256584894.988810 0.511803 Test results transmitted 1256584895.016358 0.027548 bbtest-net completed 1256584895.018441 0.002083 TIME TOTAL 71.636187 Output for hobbitd: Statistics for Hobbit daemon Up since 26-Oct-2009 15:00:11 (0 days, 00:25:02) Incoming messages : 398039 - status : 367373 - combo : 5193 - page : 183 - summary : 75 - data : 15310 - client : 9595 - notes : 0 - enable : 0 - disable : 0 - ack : 0 - config : 0 - query : 50 - hobbitdboard : 63 - hobbitdlog : 180 - drop : 0 - rename : 0 - dummy : 5 - ping : 0 - notify : 0 - schedule : 1 - download : 0 - Bogus/Timeouts : 11 Incoming messages/sec : 262 (average last 300 seconds) status channel messages: 366410 (1 readers) stachg channel messages: 34214 (1 readers) page channel messages: 5600 (1 readers) data channel messages: 15310 (1 readers) notes channel messages: 0 (0 readers) enadis channel messages: 0 (0 readers) client channel messages: 9565 (1 readers) clichg channel messages: 17 (1 readers)

Monitoring Solaris Containers
by jkwade＠futurefrontiers.com 26 Oct '09

26 Oct '09

Hello, I'm just wondering, has anyone development a separate client for Solaris containers (zones). It would be nice if the same stats were displayed except that instead of seeing the global cpu and memory, you see the individual container cpu and memory utilization. I was just wondering if anyone had something out there? Thanks.James
