Slow performance, posted by Alan Grant on Tue Jun 28 18:53:50 2022

We're up to 30 logbooks, 3.2GB data total and Elog damen has now become slow. Performance stats show 100%CPU on startup then reduces. Searches and
general UI activity is slow. It runs on a VM with 4GB memory allocated. Up to 15 concurrent users.
Trimming and archiving some data files may help but I gather overall this is underpowered hardware in this instance so what is recommended |

We have 68 logbooks and currently 60 GB data total. We run it as well on a VM, in our case with 8GB RAM.
The speed of ELOG is mostly given by the filesystem: when we had AFS it was very slow. With NFS it was better. But we now use a local disk
on the VM: that is much better. |

Hi, I have an issue with my local elog setup. it's usable but one function is just not working.
Problem
I'm getting weird error messages when trying to write or read entries from the CLI client.
I have googled a lot and most elog client examples are not giving the actual output, more like elog -h <host> -p <myport> -a ... |

Too many redirects when running behind load balancer?, posted by Tamas Gal on Tue Jul 19 11:01:00 2022

We were running ELOG for many many years in our experiments and the instance was operated on a Debian XEN server as a container. I am now trying to migrate
it into our Docker Swarm cluster and I am using the https://hub.docker.com/r/de1lz/elog-docker Docker image, which works very well with our logbooks
when I run it as a single container. However, when I put the container behind my load balancer (HAProxy) using the simple HTTP mode (which works very |

Probably you need a setting
URL = https://elog.test.km3net.de
or so in your elogd.cfg file. |

Thanks for the quick reply! Sorry, I forgot to paste the "global" part of the config, I have that URL already set:

I also tried the default configuration (example config) and it that works behind the load balancer. So I guess it's related to the password-page,
which causes this redirect loop? Our logbooks are all password protected, so when a logbook URL is clicked, it should first present the login-form, and
that's where it chokes. |

Yeah, after you enter a password, elog redirects to what it finds in "URL". You can trace that by opening "development tools" in
Google Chrome, go to "network" and watch packets going back and forth. I never worked with the load balancer, but maybe you need a different
"URL" containing a '/' at the end? |
