QUESTION
I want to run llvm-slicer
(source) for PostgreSQL main executable file (i.e., PG_ROOT/src/backend/postgres
) to carry backward slicing on PostgreSQL.
llvm-slicer
runs on top of bitcode (.bc
file). I have compiled PostgreSQL via ./configure CC=clang-6.0 && make CC=clang-6.0
, duiring which, the final compile command that link many .o
files together is (very long):
ANSWER
Answered 2022-Mar-22 at 08:54Solution: whole-program-llvm.
It provides tools for building whole-program (or whole-library) LLVM bitcode files from an unmodified C or C++ source package. It currently runs on *nix platforms such as Linux, FreeBSD, and Mac OS X.
QUESTION
I have a Power BI report pulling from SQL Server that needs to be set up for incremental refresh due to the large data pull. As the load is fairly complex (and PQuery editor is tedious and often breaks folding), I need to use a SQL query (aka a "native query" in PBI speak) while retaining query folding (so that incremental refresh works).
I've been using the nice...
...ANSWER
Answered 2021-Sep-25 at 16:48In retrospect, it's silly that I didn't try this initially, but even though the Value.NativeQuery()
M step doesn't allow a command time-out option, you can still put it in a preceding Sql.Database()
step manually and it carries forward. I also removed some common table expressions from my query which also were breaking query folding (not sure why, but easy fix by saving my complex logic as a view in sql server itself and just joining to that). Takes a while to run now, but doesn't time-out!

I'm trying to update/patch a specific GMB Local Post using curl. For this example, I'm only trying to update the summary of the post.

QUESTION
I have a problem with Postgres that others seem to have found but the solutions that are given somehow do not work for me. I explain:
WHAT I USE
- MacOS 10.15.6
- Installed through Homebrew
- PostgreSQL 12.2 on x86_64-apple-darwin, compiled by Apple LLVM version 6.0 (clang-600.0.54) (based on LLVM 3.5svn), 64-bit
THE TRIGGER EVENT
I have been doing queries without problems but some of them crash my system, here is one of the examples
...ANSWER
Answered 2020-Sep-07 at 00:45This looks like a known issue where JIT code is not signed properly and triggers security errors on MacOS. I thought a fix for this was already released, so I don't know why you would still be seeing it on 12.4, but in any event turning jit=off should fix the problem.
QUESTION
The items have category_id and location_id which has relation to tables category and location. The search form has 3 fields, 1 item keyword, 2nd is the category selection and 3rd is its location. The user has to fill all the fields in order to be able to search. The problem is that the search works only for the first input field and brings all the items with the same name but location and categories are not filtered during search...

Consider the below answer as a skeleton example for what you are looking for.
QUESTION
We started using Prometheus and Grafana as the main tools for monitoring our Service Fabric cluster. For targeting Prometheus we use wmi_exporter, with predefined parameters: CPU, system, process, service, memory, etc. Our main goal was to start monitoring our product services on the node group each instance in Azure Service Fabric.
For instance, we are using this PQuery to calculate total CPU usage in %:
100 - (avg by (hostname) (irate(wmi_cpu_time_total{scaleset="name",mode="idle" }[5m])) * 100)
and metrics +- looks realistic.
Until we started to write queries for services.
For services, sum by (process,hostname)(irate(wmi_process_cpu_time_total{scaleset="name", process=~"processes"}[5m])) * 100
, and metrics seems to be not realistic time to time, especially it is obvious after you compare it with total CPU time %. I found out an article regarding multiplying to 100 for getting % from CPU time, but in this case, I get metrics around 170% or more. Perhaps I need to divide it into the number of CPU cores?
Regarding query, I'm using the sum process because I get two different metrics for one process in two modes, user and privileged.
Can anyone please help me with the correct calculation for CPU process time total metric and transforming them to perc. ?
Thank you, I would be grateful for any help!
...ANSWER
Answered 2020-Jun-17 at 14:39I hope this will help! The result is pretty much the same as the Windows performance manager. So, for CPU % for running services (tasks, processes):

Install pQuery
PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
