Is there some application that allows system monitoring with value logging ?
Most of system monitor application usually shows current system usage (CPU/RAM/HDD/NET etc) with (sometimes) small history log (few minutes back in time).
I looking for application that allows me to check how my system was performing yesterday / week ago / etc.
Something like ex. cacti but without need of starting www server for viewing data.
Please check out our Linux monitoring tool SeaLion. You can use it to schedule any command and then review the history of outputs in the dashboard. Data retention is a minimum of 7 days which can be extended further to 14 days depending on your requirement. You can also plot graphs from the metrics extracted from those outputs with a little bit of python. We are relatively new and looking for any and all kinds of feedback.
You can make use of Enterprise Splunk to do the centralized log monitoring of your system as well as application components. For personal use free download provides indexing of up to 500MB per day which is very good limit. I am using it in Ubuntu 14.04 LTS Desktop as well on another laptop(running Ubuntu 15.10 Desktop) for doing the centralized log monitoring, debugging and visualization.
You can download it from here
I have installed it under /opt and it runs on the default port 8000.
I am using splunk to monitor all the log files under /var/log and it looks like this. I can do a free text search on any of the error or string in the log files and it works great.
You can monitor multiple directories also.
Using splunk you can avoid doing a lot of shell scripting and pattern matching and good part everything is provided out of the box.
There are other tools like ELK(ElasticSearch Logstash Kibana) as mentioned here and SiLK.
Hope this helps.
