monitoring

问题 I'm developing an ETL and must do some routines for monitoring it. At the begining, I must make in INSERT on DB to create a record informing the filename and starting process datetime. This query will return the record's PK and it must be stored. When the ETL of that file finishes, I must update that record informing the ETL finished with success and its ending process datetime. I use Text File Input to look for files that match its regex, and add its "Additional output fields" to stream. But

问题 Consider the following situation: - I am using Linux. I have doubt that my application has crashed. I had not enabled core dump. There is no information in the log. How can I be sure that, after the system restart my app was started, but now it is not running, because it has crashed. My app is configured as a service, written in C/C++. In a way: how can I get all the process/service names that have executed since the system start? Is it even possible? I know, I can enable logging and start

问题 I have developed an Android game app, and now I am looking for a tool that would monitor my apps real user performance (like CPU, memory, GPU, network, latency, etc.). I know about NewRelic's mobile APN monitoring, but it is too expensive for me. What would be other options? Thank you in advance. 回答1: If you are simply looking to understand the consumption of each of the device vitals by your application, then there are several tools on the Google Play which will help you with the same. Some

问题 Alerts defined in bosun failed as the metadata was not populated when bosun restarts. Is there a way to configure scollector to send metadata once the connection to bosun breaks? I always need to restart bosun as I keep modifying the configuration file. 回答1: Bosun stores metadata (and incident info) in redis/ledis. This information is expected to be persisted and not destroyed when Bosun is restarted. There will be a gap in Bosun's ability to receive metadata during this restart though. It

问题 I'm trying to create an app that monitors all incoming traffic and blocks it if required and if necessary, replace it with traffic from elsewhere. (preferably using a filter list made up of URL's) is there any possible way to do this? I have searched Google, and stack overflow and I have not been able to find anything relevant to my needs. thank you very much for any help in advance. 回答1: This will be tough. Android has no host file as such. I assume you will not want to develop your own

问题 I need to get info for memory and CPU usage of some process running on the machine (not the Java process). How can I do that? 回答1: It's platform dependent, but essentially use Runtime.getRuntime() to execute the appropriate command, capture its output and parse it for the data you need. 回答2: If I'm not mistaken Runtime.getRuntime is for the virtual machine and not the physical. What you are about asking is getting the physical machine information (meaning the CPU). 来源： https://stackoverflow
