CSI’s 圣骑士的监控 Saves One Client From A Major 电子邮件 Outage and Allows Us To Proactively Work On Another’s 电子邮件 Outage Issue

CSI的 圣骑士远程监控 solution uncovered two major Exchange 2010 email crisises in the span of an hour on Wednesday. 其中一个影响了不到700个用户，另一个影响了大约1350个用户.

第一个事件是圣骑士给了我们一个叫做“背压”的交换警报。. This is where Exchange believes that it is going to be unable to do its job based upon the rate of server resources (RAM and disk space) it is consuming. Exchange试图保护核心. The thing it generally does first is shutdown email flow into and out of the Exchange server. 这就引出了一个问题，“你怎么知道你发送的邮件没有被送达?? 你怎么知道你发送的邮件没有收到? 圣骑士 知道. Since CSI actively watches the alert consoles and doesn't solely rely on automated alerting to our clients, we went "old school" and picked up the phone talked to the appropriate person who didn't know they were not getting
电子邮件. 我们和他们一起解决了这个问题. A simple resource allocation change of their virtual environment and a quick reboot and those 700 users continue to do what they do 与out worrying about, “APP客户端电子邮件坏了??”

当我们结合 圣骑士的监控 与 圣骑士电子邮件防御，我们可以做得更好. 圣骑士电子邮件防御 provides us 24x7x365 SMS text alerts when mail flow into and out of an email server stops and starts. 如果停电是由于真正的灾难情况， 圣骑士电子邮件防御 immediately switches into a disaster recovery mode where the clients inbound email that cannot be delivered to their mail server is immediately available via the web. 邮件服务器可能死机了，或者大楼被毁了, 但如果你能找到上网的地方, you still are able to send and receive critical 电子邮件 until whatever bad happened is resolved. 如果这种情况是暂时的， 圣骑士电子邮件防御 will just restart the inbound and outbound mail flow automatically as soon as the connection is re-established and then notify everyone via SMS that normal mail flow is working again.

第二个Exchange事件发生在第一个事件发生一小时之后. 不幸的是，一个Exchange服务器提供了大约1,350个用户的CPU条件很高. 这会导致用户性能下降. 没有警告. 前一分钟还很正常. 下一分钟，它就在一个糟糕的地方. 圣骑士 提醒我们. We were already looking into the outage when the phone rang from the customer reporting strange performance issues in Exchange. 在这种情况下，我们无法防止性能下降. 没有人能一直做到这一点. 然而，在我们的客户知道有一个紧急问题之前，我们就知道了. 我们正在积极地努力尽快解决问题，以尽量减少停机时间. 活动开始大约20分钟后，我们解决了问题，每个人都回去工作了. 我们从警报到对该紧急警报采取行动的响应时间约为三分钟.

CSI的圣骑士监控可以避免另一个客户端过度停机

CSI的 圣骑士远程监控 "解决方案"在过去的几天里救了一个人.

上周，我们有一个网络服务提供商去现场，在几个小时后进行例行的硬件升级/交换. 停机是计划和预期的. 这是一个快速进出和恢复在线. 圣骑士 看到客户端网站下线(按计划). 然而，该网站再也没有回来. 时间一去不复返. 几个小时过去了. 很明显，有些地方出了严重的问题. 如果这种情况持续到早上，我们的委托人就会有不好的事情发生. 有2个,100 users sitting behind this one connection - many of whom would be quite angry if this wasn't resolved. We placed the appropriate after hours calls to the appropriate people and around 10:45pm the ISP re-visited the client and quickly resolved the connectivity issues created by their upgrades. 最终用户甚至不知道发生了中断. 负责那个网站的人知道因为 圣骑士 不管他们是否站在那里，他们都在全天候监控那个地点吗. We knew not just to rely on an automated "you are down" alert because we try very hard to have interactive discussions 与 our clients and go the extra mile in trying to keep them healthy. 在这种情况下，这是一些下班后, 实时监控“人”——只是为了确保一切顺利. It is impossible to know everything that is going on, or about to go on, 与 your network.

通过覆盖24x7x365 圣骑士远程监控 we can provide you 与 the ability to know things about your network that are impossible to know on your own. 要筛选的数据实在太多了. In both these instances we were able to uncover substantial issues and deal 与 them before they became a major crisis 与 lots of unhappy users.

CSI通过飓风艾琳监控我们客户的网络

飓风艾琳逼近纽约, CSI used our 24x7x365 圣骑士的监控 service to help our clients prepare their computers and networks for the impending hurricane. We were able to quickly identify all the uninterruptible power supplies (aka batteries) under management which had bad batteries or other hardware issues. Equipment plugged into these battery units had a greater than normal exposure to power fluxuations.

一个客户网站打算在风暴期间关闭他们的全部业务. Before they shut their equipment down we identified a server that was compromised 与 bad drives in a RAID array and other hardware issues. Our concern was that since this critical server already had a failed redundant component plus other issues, 它可能会被关闭，永远不会重新上线.

意识到修复服务器的时间是至关重要的, we were able to use 圣骑士's remote management tools to remotely reach into the server at 12am Saturday as the storm approached to rebuild the redundant drive and re-establish full redundancy before the server was actually shutdown. 客户从不需要起床. 没人非得出现才能让我们进去, 关掉闹钟，打开通往服务器壁橱的多扇门. 在我们的工作完成之后, 服务器像客户端计划的那样宕机，在风暴过后恢复正常.

During the storm we pro-actively monitored our customer’s networks and provided active status updates as we saw buildings and servers go down due to power failures throughout the region. By looking at the previous alerts and querying the power supplies we were able to identify the difference between "no power" and actual equipment failures.

Once the storm subsided on Sunday we were able to pinpoint exactly what buildings were offline around the region. Then as those buildings came back on-line we were able to pinpoint exactly what equipment inside each building did not turn back on. From there we had a list of devices for either the client's technical staff or CSI的 staff to investigate.

Sunday night I was personally watching over our client's networks via the 圣骑士 monitoring console. 在这个过程中，我家里停电了. 我走到外面，启动了发电机. 然后，我打开了笔记本电脑上的Verizon无线网卡，一点都没漏掉.

CSI的 office has an ample standby generator of its own and an excellent internet connection so our 24x7x365 monitoring continued regardless of the storm conditions.

有一次，尽管洪水泛滥，周一早上还是来了, road closures and massive power outages in some areas most of our clients went back to work 与 their computer networks operating much like they did on Friday when they left for the weekend.

这就是CSI的圣骑士监控所做的.
