How does the mailsending in SA work: * Servers Alive creates the mail and sends this to our mail-queue component.
* the mail-queue component starts sending This means that if there are a lot of mails to be send, SA is able to generate them quickly and send them to the queue, and the queue then sends them one-by-one. Sending a mail is slower then generating a mail. That why we added the queue in between the generation and the actual sending. Without the queue you would get a slow down in the checking too. The only thing we could do, is to make the queue send with several mail-sender threads…… dirk From: Servers Alive Discussion List [mailto:[email protected]] On Behalf Of [email protected] Sent: Thursday, September 22, 2011 5:46 PM To: Servers Alive Discussion List Subject: [SA-list] mail delay when checks are DOWN? Hi, we had 166 DOWN checks this morning, normally we have some 0 to 5. This were all PING checks (SK) each with 2 dependant checks (1 NT process, 1 NT service). Yes, that was bad! The systems were „not existent“, so the PING was not executed: ERR: problem resolving the name (BKKXENAPP077) ERR: problem resolving the name (Winsock could not resolve the host name (11004)) The alert is configured to send SMTP mail when 1 time down (and when up again), the checking schedule starts 5:45. Check times: every 3 minutes. The status summary mail is configured to be sent “approximately at” 5:50, our normal check cycle lasts about 10-12 minutes, so I expect the status mail to be there around 6:05. According to the logfile, the check cycle ( 567- 567) started at 05:48:39, the next one ( 568- 568) at 06:07:07. Now we had this effect: The 1st alert mail: generated 05:48:50, received 05:48:55 The 10th alert mail: generated 05:57:55, received 05:58:38 The ~100th alert mail: generated, 06:01:34 received 06:14:54 The last alert mail: generated 06:03:32 , received 06:23:35 The status summary mail: generated 06:04:05, received 06:23:45, the header is looking like this: Received: from BKKSALIVE002.bkk-mobiloil.de (10.96.65.5) by bkkmail003.bkk-mobiloil.de (10.96.65.132) with Microsoft SMTP Server id 14.1.289.1; Thu, 22 Sep 2011 06:23:45 +0200 To: <[email protected]> From: <[email protected]> Subject: Servers Alive: down: 166 - up: 823 - maintenance: 60 Date: Thu, 22 Sep 2011 04:23:45 +0000 Message-ID: <[email protected]> X-Mailer: Woodstone Servers Alive version 6.3.2407 X-Priority: 2 X-Info: http://www.woodstone.nu/salive (http://www.woodstone.nu/salive) X-WSSAID: 44540120110922.SA632407-1 MIME-Version: 1.0 Content-Type: text/plain Return-Path: [email protected] X-MS-Exchange-Organization-AuthSource: bkkmail003.bkk-mobiloil.de X-MS-Exchange-Organization-AuthAs: Anonymous X-MS-Exchange-Organization-AVStamp-Mailbox: MSFTFF;1;0;0 0 0 X-OLX-Disclaimer: Done X-Auto-Response-Suppress: DR, OOF, AutoReply Who is generating this delay?
