monitoring

问题 I am aware of " SQL Server Profiler ", But is there any tools or methods available to monitor the issued sql queries from the client machine? Some of the things currently in my mind are: 1) The SysInternals ProcMon can log and tell when the executable process on client machine connects to sql server. Any similar but more advanced tools available to tell more data? 2) Any debug version or instrumented version of client libraries and APIs available for client machine to allow such operation?

问题 Are there any standard metrics publishing packages for node.js? I'm not asking about general metrics libraries, but rather packages that produce a specific set of metrics (e.g. http QPS, runtime memory usage, gc stats, etc...) If you wanted to offer a monitoring service for node.js users, what would you monitor? 回答1: I believe that Node Application Metrics ('appmetrics') provides what your looking for. This is a module that provides a set of metrics about a running Node.js process, rather

问题 I want to monitor data size transferred into and out of my database. I'm using a Java client application & Firebird v2.5 database. Both are deployed locally on one machine. It turns out that Firebird does not provide any monitoring variable like "Bytes_received" or "Bytes_sent" that are available in MySQL. as discussed in Is there any way to monitor the size of data transfer In/Out of database So I set up some tools to capture the local traffic and analyse it. WireShark - to analyse the

问题 I am developing a stock management system using Java Swing Framework and Firebird v2.5 My aim is to calculate the amount of data being transferred In/Out of the database for a defined interval. I've been searching online, found out that in MySQL they have these monitoring variables Like "Bytes_received" or "Bytes_sent" which can be used to get Session oriented or Global count for bytes being receive & sent respectively. Is there any better approach to calculate that? 来源： https://stackoverflow

问题 After enabling query store, how to find who executed the query. For example, in case of trace collection, there is TRC file which will get the hostname and program details for query and in case of Extended-Events, we have XEL file which will get the hostname and program details. We tried code SELECT des.program_name, des.host_name, * FROM sys.query_store_query_text qt -- Query Text JOIN sys.query_store_query q ON qt.query_text_id = q.query_id -- Query Data JOIN sys.query_store_plan qp on qp

问题 I'm using AWS Cloudwatch to monitor application log files on my AWS EC2 instances. Is there a way to include Custom data (I.E. stack trace) in the Cloudwatch Alert when it is triggered by the metric I define? 回答1: I ended up routing the alert event to a REST service I wrote rather than to the SNS notification group. The web service uses the "event name" and timestamp to generate a custom notification. It pulls diagnostic information from several services, including our ELK stack, and includes

问题 I am trying to launch the ColdFusion Server Monitor on a Windows Server 2003 (Web Edition) machine running ColdFusion 8 (ver. 8,0,0,176276). It is running in stand-alone configuration.
