Plugin performance oddities #786
Comments
|
@mansilladev do you see any error in the Kong error log? |
|
Earlier today I did (of course, I wiped my error log) -- something about a dubious connection (may have been related to a keepalive value that was super high). However, on those latest stats that I just posted above, no, there aren't any errors being logged. |
|
The logging plugins perform the actual logging asynchronously in a function being triggered by an I can think of two possible issues:
The I will try to replicate this problem, what version of Kong are you using? |
|
For mashape-analytics, I have run similar benchmarks on 0.5.4 (with a much higher concurrency) and I did not experience any loss. If you want to find out how many ALFs exactly are being sent to Galileo, you can switch your logging level to If you experience any loss (number of ALFs sent != number of requests) happy to hear about it so we could improve it. |
|
@mansilladev I tried to configure an API with only And experienced 0% loss on the file log. I then tried to install the Galileo plugin on top of it, so that every request would be logged to both file-log and Galileo, and 0% loss on both. I tried this on the latest version of Kong. |
|
I'm on the latest version of Kong running on my MB Pro (from the .pkg). With Galileo and Runscope plugins I might chalk it up to the network; however, with the file log, that wouldn't make sense. I'll dial up the debug level and see if the logs reveal any more information. I'll also refer to a non-cloud-based backend API to keep all traffic isolated to my local machine. I'll post results later tonight. Thanks everyone. |
|
Well, it looks like it must have just been something on my localdev. Things seem to be working just swell now syncing into Galileo and Runscope. The file-log plugin -- I am seeing a bunch of |
That shouldn't be the case, could you paste some lines that show this symbol? |
|
@thefosk It's actually a null value.. and man alive, there are a ton of them. Just reset the file, restarted kong, launch about 100 requests at an endpoint and the log file ended up with 5 visible lines.. and one of those lines had 228,000 nulls. |
|
@mansilladev just checking in on this issue - were you able to replicate this problem? |
|
Closed from lack of update. |

### Summary
#### 2.6.0
```
Release 2.6.0 Tue February 6 2024
Security fixes:
#789 #814 CVE-2023-52425 -- Fix quadratic runtime issues with big tokens
that can cause denial of service, in partial where
dealing with compressed XML input. Applications
that parsed a document in one go -- a single call to
functions XML_Parse or XML_ParseBuffer -- were not affected.
The smaller the chunks/buffers you use for parsing
previously, the bigger the problem prior to the fix.
Backporters should be careful to no omit parts of
pull request #789 and to include earlier pull request #771,
in order to not break the fix.
#777 CVE-2023-52426 -- Fix billion laughs attacks for users
compiling *without* XML_DTD defined (which is not common).
Users with XML_DTD defined have been protected since
Expat >=2.4.0 (and that was CVE-2013-0340 back then).
Bug fixes:
#753 Fix parse-size-dependent "invalid token" error for
external entities that start with a byte order mark
#780 Fix NULL pointer dereference in setContext via
XML_ExternalEntityParserCreate for compilation with
XML_DTD undefined
#812 #813 Protect against closing entities out of order
Other changes:
#723 Improve support for arc4random/arc4random_buf
#771 #788 Improve buffer growth in XML_GetBuffer and XML_Parse
#761 #770 xmlwf: Support --help and --version
#759 #770 xmlwf: Support custom buffer size for XML_GetBuffer and read
#744 xmlwf: Improve language and URL clickability in help output
#673 examples: Add new example "element_declarations.c"
#764 Be stricter about macro XML_CONTEXT_BYTES at build time
#765 Make inclusion to expat_config.h consistent
#726 #727 Autotools: configure.ac: Support --disable-maintainer-mode
#678 #705 ..
#706 #733 #792 Autotools: Sync CMake templates with CMake 3.26
#795 Autotools: Make installation of shipped man page doc/xmlwf.1
independent of docbook2man availability
#815 Autotools|CMake: Add missing -DXML_STATIC to pkg-config file
section "Cflags.private" in order to fix compilation
against static libexpat using pkg-config on Windows
#724 #751 Autotools|CMake: Require a C99 compiler
(a de-facto requirement already since Expat 2.2.2 of 2017)
#793 Autotools|CMake: Fix PACKAGE_BUGREPORT variable

#790 CMake: Build tests/benchmark/benchmark.c as well for
a build with -DEXPAT_BUILD_TESTS=ON

accordingly
#736 docs: Improve use of "NULL" and "null"
#713 docs: Be specific about version of XML (XML 1.0r4)
and version of C (C99); (XML 1.0r5 will need a sponsor.)
#762 docs: reference.html: Promote function XML_ParseBuffer more
#779 docs: reference.html: Add HTML anchors to XML_* macros
#760 docs: reference.html: Upgrade to OK.css 1.2.0

On an API, I have
mashape-analytics,file-logandrunscope-logactivated (the last one is one I'm developing). Anyhow, when I runsiegeorabwith fairly conservative numbers (100 requests total, 2 concurrent), both of the clients show 100% success; however, the amount of the requests that make it to the plugins varies greatly. For example:Can someone point me in the right direction to find out where some of this loss might be occurring?
The text was updated successfully, but these errors were encountered:
