perfSONAR User Q&A and Other Discussion

[Zachary Newell <>]

I would try to perform the install on a system connected to the internet and bring it into your environment. The logstash-plugin executable wants to download the plugin from an HTTPS server, and I'm not familiar with if it's capable of performing an offline install.

Here's what I would do if I were in your situation:

1. Prepare perfsonar in an LXC container, then export it and import it.
2. Prepare an install on a drive you can add to the system or copy from with a command like dd(1).

⚠ External Email: 

Hi Zachary,

I run the command to reinstall the logstash plugin. It says artifacts.elastic.co:443 is not reachable. 

Our perfSONAR boxes are within RnE network, and they don't have access to the Internet. Any other ways to install the plugin?

[root@lat-sask1pfs1 tzhang]# /usr/share/logstash/bin/logstash-plugin install /usr/lib/perfsonar/logstash/plugin/logstash-output-opensearch.gem

Using bundled JDK: /usr/share/logstash/jdk

OpenJDK 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release.

ERROR: Something went wrong when installing /usr/lib/perfsonar/logstash/plugin/logstash-output-opensearch.gem, message: Network is unreachable - Failed to open TCP connection to artifacts.elastic.co:443 (Network is unreachable - Network is unreachable)

It looks like part of the postinst script failed. Are you running perfsonar in a container? Certain packages (opensearch) want systemd running to install properly. It looks like this script enables that plugin on Debian-based systems:

https://github.com/perfsonar/logstash/blob/f1925a123c4ae60e34bc43e2b70ef234a5bf78db/perfsonar-logstash-output-plugin/perfsonar-logstash-output-plugin/unibuild-packaging/deb/perfsonar-logstash-output-plugin.postinst

Here's the exact command

```

/usr/share/logstash/bin/logstash-plugin install /usr/lib/perfsonar/logstash/plugin/logstash-output-opensearch.gem

```

That might get you further along. In my opinion, it might be easier to start over: IE

apt remove --purge $package

apt install $package

The purge option should remove configuration files copied from the .deb package but you also might have to do some housekeeping in /etc/perfsonar/logstash.

Thank Zachary,

The logstash service is running, however, from the log messages, there are some fatal errors there, "Unable to load opensearch plugin". Any suggestions?

HTTP 503 from apache2 likely means your logstash service is down.

Check that it's running:

systemctl status logstash

Look for errors in the log file:
/var/log/logstash/logstash-plain.log

Hi Mark,

The testing data is still not archived to LogStash and OpenSearch. Not sure which part went wrong.

I checked the pscheduler log. The log filled with something like this:

5.0 replaced Esmond with LogStash and OpenSearch.  There is a backward-compatibility layer for Esmond, but it is read-only.  If your tasks are archiving to the local system, they will need to use the HTTP archiver and post it to LogStash instead.  These two sections of the documentation should get you there:

This is a bug in pScheduler that appears to have been introduced in the last release.  I’ve already corrected it and added it to the pipeline for the next bugfix release, which should happen sometime during the week of May 1.

 

Based on what I could pull out of the API on your system, these are the tasks that are failing:

As a stopgap, removing the ‘sendwait’ option from your trace tasks won’t trip the faulty code.  Note that this will alter the character of the measurement.
