Based on the score and set limits for success, Kayenta can automatically promote or fail the canary, or trigger a human approval path. Kayenta fetches user-configured metrics from their sources, runs statistical tests, and provides an aggregate score for the canary. This allows teams to easily set up an automated canary analysis stage within a Spinnaker pipeline. Kayenta is integrated with Spinnaker, an open-source multi-cloud continuous delivery platform. It gives enterprise teams the confidence to quickly push production changes by reducing error-prone, time-intensive and cumbersome manual or ad-hoc canary analysis. Today, Google and Netflix are pleased to announce Kayenta, an open-source automated canary analysis service that allows teams to reduce risk associated with rolling out deployments to production at high velocity.ĭeveloped jointly by Google and Netflix, Kayenta is an evolution of Netflix’s internal canary system, reimagined to be completely open, extensible and capable of handling more advanced use cases. Now, I am not having any problem since about two-and-a-half months.Ĭonclusion, when suffering from such a problem, clear your hosts file and use some "Reliable" Internet Security suite.To perform continuous delivery at any scale, you need to be able to release software changes not just at high velocity, but safely as well. Then I switch to Norton Internet Security, removed Spybot SnD. That eventually leads to the conclusion that both the anti-viruses I had installed were not doing enough to stop the Spyware. And in fact, I had scanned my laptop several times in a month or so to remove frequent Spyware infections, which used to block the Internet on the laptop. I removed all the entries in hosts below the default ones, and amazingly, the problem was solved.Īnother thing that I found was that such entries are written to the file by Spybot SnD. Whenever I connected to Internet, the servicehost.exe process looked up the file, which was unusually large. I opened the hosts file and found that its size was about 1.2 MB with few thousand entries, instead of just about 1KB file. On researching further, I found somewhere that that culprit may be the hosts file in Windows/System32/drivers/etc directory. What could be the cause of the problem and what can I do to resolve this? Secondly, I can't uninstall the Trend Micro Internet security Suite since it still has few months before it expires and is proving me reliable protection. I can't do without the Google Chrome (of course, by not using it) because of its immensely useful and indispensable features both during browsing and development. I just can't figure out who is the culprit. Stopping the Protection by the Trend Micro Internet Security doesn't help either (I am not able to stop its services though). That makes think that Chrome is the root of the problem, but again, tracing coreServiceShell.exe takes me back to Trend Micro Internet Security. Also, when I close the Chrome, while Internet is connected, svchost.exe continues to hog CPU but coreServiceShell.exe leaves the race. Seeīut if I use Google Chrome, the coreServiceShell.exe hogs both CPU and RAM.Īt this point, if I disconnect the Internet, the CPU and RAM usage by coreServiceShell.exe continues to be high till I close the Chrome. That kind'a makes me think that Trend Micro may be the root of the problem.Īfter further testing, I found that if I use IE or Firefox to browse the Internet, immediately after connecting to Internet, things are normal. Going into the details, I found that high CPU usage of svchost.exe is caused by Network Location Awareness service.Īnd the high CPU usage of coreServiceShell.exe is caused by Trend Micro Titanium Internet Security 2012. The coreServiceShell.exe consumes a lot of RAM also. Whenever I connect to Internet, either svchost.exe or coreServiceShell.exe or both hog the CPU. Since past few days, my laptop is facing a serious problem. I am having a laptop running on Windows 7 Ultimate 32-bit.
