Everything was running fine up until 7/30 and then all of sudden syslog-ng is having problems pushing messages to kafka at a quick pace.</div><div class=""><br class=""></div><div class="">I've updated to 3.28.1 and it's still having problems. I was using disk buffering but I removed it an d doesn't seem to be the bottleneck.</div><div class=""><br class=""></div><div class="">I feel it's something with syslog ng as I can use the kafka perf test to push messages at a very quick rate to the cluster. I was able to push 1 million 1k test messages in several seconds. Syslog-ng seems to be able to only push a couple of messages a second.</div><div class=""><br class=""></div><div class="">Any thoughts on what could be tanking it's performance? It's running on Amazon Linux 2.</div><div class=""><br class=""></div><div class="">I've rebuilt our base image with the latest version so we can switch between kafka-c and the java version however since the kafka-c topic can't be templated at the moment until a pull request is released I can't switch to it to see if it fairs better.</div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><span style="color: rgb(0, 0, 0); orphans: 2; text-align: -webkit-auto; widows: 2;" class="">Ronald Fenner</span></div><div class=""><div style="color: rgb(0, 0, 0); font-family: Helvetica; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-variant-east-asian: normal; font-variant-position: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: -webkit-auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;" class=""><div style="color: rgb(0, 0, 0); font-family: Helvetica; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-variant-east-asian: normal; font-variant-position: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: -webkit-auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;" class=""><div style="color: rgb(0, 0, 0); font-family: Helvetica; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-variant-east-asian: normal; font-variant-position: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: -webkit-auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;" class=""><div class=""><div class="">Network Architect</div><div class="">Game Circus LLC.</div></div><div class=""><br class=""></div><div class=""><a href="mailto:rfenner@gamecircus.com" class="">rfenner@gamecircus.com</a></div></div></div></div>
