Splunk archiver app5/5/2023 Oceans 3.0 comprises both tools to manage the data acquisition and archival of all instrumental assets managed by ONC as well as end-user tools to discover, process, visualize and download the data. Oceans 2.0 was the name for this software system from 2006–2021 in 2022, ONC revised this name to Oceans 3.0, reflecting the system’s many new and planned capabilities aligning with Web 3.0 concepts. This paper describes Oceans 2.0 and Oceans 3.0, the comprehensive Data Management and Archival System that ONC developed to capture all data and associated metadata into an ever-expanding dynamic database. The first data streams from the cabled instrument nodes started flowing in February 2006. Ocean Networks Canada (ONC) commenced installing and operating two regional cabled observatories on Canada’s Pacific Coast, VENUS inshore and NEPTUNE offshore in the 2000s, and later expanded to include observatories in the Atlantic and Arctic in the 2010s. The advent of large-scale cabled ocean observatories brought about the need to handle large amounts of ocean-based data, continuously recorded at a high sampling rate over many years and made accessible in near-real time to the ocean science community and the public.

In order to be able to read /var/log/messages and /var/log/secure, we will run the following command as root user: setfacl -m g:splunk:r /var/log/messages If thenįILE_LINES=`wc -l $AUDIT_FILE | cut -d " " -f 1`Īwk -v START=$SEEK -v OUTPUT=$SEEK_FILE 'NR>START ' $AUDIT_FILE | tee $TEE_DEST | /sbin/ausearch -i 2>/dev/null | grep -v "^-" # assertHaveCommandGivenPath /sbin/ausearch SEEK_FILE=$SPLUNK_HOME/var/run/splunk/unix_audit_seekfile # See the License for the specific language governing permissions and ![]() # WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. # distributed under the License is distributed on an "AS IS" BASIS, # Unless required by applicable law or agreed to in writing, software # You may obtain a copy of the License at # you may not use this file except in compliance with the License. # Licensed under the Apache License, Version 2.0 (the "License") Therefore, I changed the rlog.sh under /opt/splunk/etc/apps/Splunk_TA_nix/bin/ to the following: #!/bin/sh Unfortunately, the rlog.sh script, which is responsible for reading the /var/log/audit/audit.log file, is not working for me. # This file controls the configuration of the audit daemonĪfter that, we restart the auditd daemon with the following command: system auditd restart In order to read the /var/log/auditd/audit.log, we will change in /etc/audit/nf the log_group to splunk: # As we installed Splunk as splunk user, which is a non-root user, we have to perform some changes in order to be able to read these log files. In my opininon, the files /var/log/messages, /var/log/secure and /var/log/audit/audit.log are worth to collect. You can enable it by changing the disabled value to 0 and adding the index value: # Copyright (C) 2018 Splunk Inc. The first part of the nf configuration file uses different bash scripts to collect information about the Linux server. We will copy the nf configuration in the new folder: cp default/nf local/ Instead, you should create a local folder and make your changes there: mkdir local ![]() Normally, you should never edit the files in an apps default folder. We connect over terminal to our Splunk server and navigate to the Splunk Add-On for Unix and Linux folder as splunk user: cd /opt/splunk/etc/apps/Splunk_TA_nix In the next steps, we will configure the Splunk Add-On for Unix and Linux. tgz file by clicking on Durchsuchen/Choose and then click on Upload: We login to our Splunk instance and click on Manage Apps: In the first step, we will download Splunk Add-On for Unix and Linux from splunkbase: We will monitor the logs of the Linux Server running Splunk. This tutorial assumes that you have already installed Splunk as described in this blog post. We will cover different logging/monitoring options for Linux Server using Splunk Enterprise. In this blog post, I will explain how to monitor a Linux Server with Splunk.
