I am able to set up Splunk in OpenShift and install splunk-connect using helm. I did create indexes and enable HEC (HTTP Event Collector) and created a HEC token. Splunk HEC values.yaml is completed with appropriate values. All pods are up and running but i am seeing no OpenShift logs in Splunk. Error I am seeing

Did you try setting insecureSSL: true in the values.yaml file and then redeploying?

I've seen similar questions being asked on stack overflow but none of them seem to solve my issue properly. I have recently upgraded my system from Ubuntu 16.04 to Ubuntu 17.10 . Since then, I've been experiencing a problem with mysql where I'm not able to start it up properly and it shows the following error:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket
'/var/run/mysqld/mysqld.sock' (2)
I've searched for many solutions online and as a last effort also tried uninstalling and reinstalling but the problem resurfaces after a few days or few attempts. Upon running "service mysql start", it shows:
Job for mysql.service failed because the control process exited with
error code.
See "systemctl status mysql.service" and "journalctl -xe" for
details.
Upon running the suggested commands it shows the following logs:

Every time this happens, I uninstall mysql and reinstall(server not client), and then it works alright for the first few attempts, then it goes back to same situation. Thanks in advance!

When I read a csv file in my Jupyter notebook I got the following output

I want to change the first column content into a day-month-year format in order to calculate the years passed since first observation (which in this case is my last row).
I tried converting the column using string, then using a for loop (Suppose the name of my file is "ebola"
dias = string.(ebola[:,1])
for i = 1:length(dias)
dias[i] = DateTime(dias[i], "d-m-y")
end
After that, I got this error message
ArgumentError: Unable to parse date time. Expected directive DatePart(d) at char 1
I suppose this error arises because the string has a non-conventional format to manipulate it, with four "" symbols and some backslashes:
"\"25 Nov 2015\""
I must add that when i type, for example:
length("\"22 Mar 2014\"")
result is 13 when you can count 17 characters so clearly backslashes are making some "noise".
What can I don to convert the string in a proper format in order to perform the tasks I want to do?
Any help will be much appreciated.
The reason is that "\"22 Mar 2014\"" is a string containing " characters inside. You can check it by printing it:
julia> s = "\"22 Mar 2014\""
"\"22 Mar 2014\""
julia> print(s)
"22 Mar 2014"
In order to parse the date use a proper format string, e.g.:
julia> Date(s,"\"d u y\"")
2014-03-22
Here is how you can perform the conversion from your array:
julia> x = ["\"25 Nov 2015\"" 28637 11314 3804 2536 10675 4808 14122 3955
"\"18 Nov 2015\"" 28634 11314 3804 2536 10672 4808 14122 3955

I checked databases are present. Users with passwords are valid.
I tested if console works. Yes it works.
rails console production
I was able to create new record and also update existing one!
This makes me think what is wrong then ? If just for webservice database is not working ?
So from where this problem comes ?
Any tip would be great.
thanks
I solved this easily by reverting to mysql, and adding the port number 3306 to my database.yml
*for the record my app is on shared hosting on Bluehost.
previous database.yml:
development:
adapter: mysql2
database: my_db
encoding: utf8
username: my_username
password: my_password
host: localhost
reconnect: true
current database.yml:
development:
adapter: mysql
database: my_db
encoding: utf8
username: my_username
password: my_password
host: 127.0.0.1
reconnect: true
socket: mysql
port: 3306
On my website VPS the MySQL goes down quite often, once a day lately.
I've looked in my syslog and seems like it is an Out Of Memory error.
Is my MySQL not configured the right way or is does my VPS not have enough memory for what I'm running on it?

Looks like the VPS I am running doesn't have enough RAM for the amount of website and databases I am running on it. I'll be upgrading my VPS to one with 1GB of memory.
I originally posted this at Super User, but now think it should be here instead...
I'm trying to port my RoR webapp over to a DreamHost VPS. I've upgraded the VPS --> Ruby 1.9.2 from 1.8.7 and am using Rails 3.0.1 and the mysql2 (0.2.6) gem. I'm getting the following error when trying to start mongrel:
/usr/bin/ruby1.8: symbol lookup error: /home/USERNAME/.gems/gems/mysql2-0.2.6/lib/mysql2/mysql2.so: undefined symbol: rb_intern2
...so I tried using the mysql (2.8.1) gem instead and get the following error:

I'd prefer to use mysql2, so that's the preferred solution I'm looking for, but I will certainly appreciate input on either problem.
I'm not encountering any problems such as this in my development environment (which is windows)
You'd mentioned that you're running Ruby 1.9.2 but your error dump looks like it's running Ruby 1.8 I'm not sure that this would cause the problem or not but it seems like a potential issue.
I'd uninstall ruby1.8 and see if it fixes anything.
sudo apt-get remove ruby1.8
