MYSQL PHP Charting epoch Time series data

I was writing PHP code to generate EMC VMAX performance reports / charts stored in MySQL DB. As we know that Unisphere REST API output performance metrics in epoch (13 digits) format (milliseconds). As an example, to draw a line chart for Frontend Director’s Read Response Time with X axis / Abscissa as epoch time. I’ve used below query to generate the datapoints to draw the chart using pChart

SELECT TIME(FROM_UNIXTIME(timstamp/1000)) as TIME, ROUND(AVG(perfval),2) as wrt FROM vmax_perf

where DAYOFMONTH(FROM_UNIXTIME(timstamp/1000)) = DAYOFMONTH(DATE_SUB(curdate(), INTERVAL 1 DAY))

and objname =’fe’ and perfparam =’ReadResponseTime’

group by HOUR(FROM_UNIXTIME(timstamp/1000))

Let me explain the above statement

TIME(FROM_UNIXTIME(timstamp/1000)) :: Extract Time from the epoch (13 digit) format in millisecond

ROUND(AVG(perfval),2) :: Average of Read Response Time per Hour rounded output to 2 digits after decimal point

DAYOFMONTH(FROM_UNIXTIME(timstamp/1000)) = DAYOFMONTH(DATE_SUB(curdate(), INTERVAL 1 DAY)) :: Extract day (ex. ’12’ from 12th Nov 2016 where current date is 13th Nov 2016) and display the data points

group by HOUR(FROM_UNIXTIME(timstamp/1000)) :: Print the datapoints for every hour

Stay Tuned for more updates on MySQL queries to generate charts for Daily, Weekly, Monthly and Quarterly performance reports / charts. Thanks for stopping by… Please leave your comments / suggestions.

EMC VMAX Storage Automated Performance Report

This blog is being written as a companion to my previous blog on Automated EMC VMAX Capacity Reporting

platform-vmax

In recent times, we’re asked to develop scripts to capture performance metrics from EMC VMAX storage. There is a ‘symstat’ command with many attributes to capture performance metrics information from the array. But this command was not fulfilling all our requirements. While exploring various options and consultation with EMC support / community we decided to try Unisphere / RESTAPI.

So far I was using Perl as THE LANGUAGE to talk to my storage arrays. But I was forced to switch over to Python which works best with REST API / JSON. Additionally, there are lots of code out there on RESTAPI written in Python. So it is easy to ‘get inspired’ by those codes and write customized code for our requirements. So this would make me yet another ‘Pythonistas’ 🙂

This is my first ever Python (version 2.7 on GNU/Debian Linux) script to capture EMC VMAX Performance Metrics retrieved from Unisphere for VMAX (version 8.2) via RESTAPI. I’ve referred this Python script to develop custom script to suit our requirements. Many thanks to Matt Cowger (mcowger) for sharing the script in Github.

There are plenty of metrics that can be captured using this script but I’ve written a simple code for demo purpose to print few metrics in CSV format which can be either imbibed by excel for further reporting / charting or injected to MySQL DB to do many stuffs…

Here is the sample + cropped output for reference. In the below table timestamp (column B) is in epoch format which is converted to MYSQL datetime format via INSERT query

P.S: I’ve changed VMAX serial number for various factors🙂

EMC Isilon – Quick CLI help

I was trying to head start with Isilon CLI to automate some of the manual stuffs that we do on regular basis. Though I found the CLI guide from support site; I was not happy with explanations or syntax etc…

After googling for some time I found below sites are useful and provided list of important commands with crisp description. I got what I wanted to use in the script and saved time and energies!!

EMC VMAX Storage Automated Capacity Report

EMC VMAX3

Storage capacity reporting has become a tedious task these days unless we don’t have tools in place. These tools are not as cheap we can think of. There are additional layers added to it to hype and increase its value in market. But if customer ask a storage admin to run the report manually then its a nightmare for the admins.

We always want to go by the easy way which means GUI / EMC Unisphere but for reporting this doesn’t helps to customize and fulfill the customer requirements . EMC SYMCLI / Solutions Enabler can be used effectively here to address this issue. We can use SYMCLI to automate these manual reports. By means of automation, we can ensure quality, timely and error-free reports are generated which can be scheduled via CRON or Tasks Scheduler to send it directly to the stakeholders. SYMCLI built-in supports XML formatted output of the commands which would become easier to parse the information using XML supported programming language.

I’ve developed PERL scripts to generate Storage Pool capacity and Disk capacity report for multiple VMAX storage arrays which are managed from the SYMCLI / Solutions Enabler server. Following are the benefits of using this script.
1. Generates Pool capacity report for all storage arrays which has columns – SYM ID,MODEL,TOTAL USABLE POOL CAPACITY TB,TOTAL USED POOL CAPACITY TB,TOTAL FREE POOL CAPACITY TB, TOTAL POOL UTILIZATION %, TOTAL POOL SUBSCRIBED %
2. Generates Disk capacity report for all storage arrays which has columns – SYM ID,MODEL,TOTAL EFD,TOTAL FC_SAS,TOTAL SATA_NLSAS,FORMATTED EFD CAPACITY GB,FORMATTED FC_SAS CAPACITY GB,FORMATTED SATA_NLSAS CAPACITY GB, TOTAL FORMATTED CAPACITY GB, UNFORMATTED EFD CAPACITY GB,UNFORMATTED FC_SAS CAPACITY GB,UNFORMATTED SATA_NLSAS CAPACITY GB,TOTAL UNCONFIGURED CAPACITY GB,TOTAL UNFORMATTED CAPACITY GB

Output generated from the scripts will be in the form of CSV format. This is information can be plugged into desired format and generate reports with Pivots, charts etc…

Please find below  sample output for reference.

Pool Capacity Report:

2016-02-17 21_21_57-Book1 - Excel

Disk Capacity Report:

2016-02-17 21_22_41-Book1 - Excel

P.S: I’ve removed VMAX serial number for various factors 🙂

If interested, please reach out to me to get these PERL scripts.

Isilon – Download support logs from CLI

Recently, we’re trying to download Isilon log files for troubleshooting purposes. We’re supposed to download log files and then upload to EMC support portal.

We tried to download from the GUI using all major browsers but download was not possible (could be due to huge log file size summing up to 3 GB). Later we tried to do WinSCP which was failing to connect due to network connectivity issues.

Finally, we’re able to succeed by the help of Linux box which was in the same network. We used the simplest method ‘scp’ for copying files from Isilon to Linux box and from there we’re able to upload the files to EMC support portal.

Below was the command and log file path under ‘ifs’ directory structure in Isilon.

scp root@12.31.12.24:/ifs/data/Isilon_Support/pkg/IsilonLogs-ISILONCL01-20151215-042443.tgz .

We downloaded the file ‘IsilonLogs-ISILONCL01-20151215-042443.tgz’ to local directory (. means current directory) using the root credentials of the Isilon cluster having IP: 12.31.12.24

Alternatively if we don’t have a Linux box we can failback on cygwin to do the same on Window$ if WinSCP is not working.

I hope this command would help us if we need to download multiple files in a jiffy of time.

VMAX Storage Group Report

Here is the the simplest way to generate a simple VMAX Storage Group’s allocated capacity report.

Run the below command

symsg -sid 1234 list -v > sglist.txt

Above command show each SG’s information in details along with Devices, type and capacity. We’ve redirected the output to a text file called ‘sglist.txt’. To produce a simple report using the above output; we need to use the below grep command.

grep ‘Name:\|2-way\|TDEV’ sglist.txt > out.txt

Above command greps lines having name of storage group, devices with 2-way mirror config and thin devices which are redirected to another text file called ‘out.txt’. We can see the devices with Status, capacity etc… which is sufficient to produce / calculate allocated storage capacity.
