QUESTION
There's one DB table 'SiteTransactions' (in Sql Server) which currently has the records in following sample format
Id TransactionType SiteGroup SiteName TransactionTime 1 Create SG1 TestSite1 2021-08-27 19:22:26.4318370 2 Delete SG1 TestSite1 2021-08-28 09:22:26.4318370 3 Create SG2 TestSite2 2021-08-28 10:12:26.4318370 4 Create SG1 TestSite3 2021-08-29 19:22:00.4318370 5 Delete SG2 TestSite2 2021-08-30 08:04:26.4318370 6 Create SG2 TestSite2 2021-08-31 20:18:26.4318370 7 Delete SG2 TestSite2 2021-08-31 20:20:26.4318370This table stores all of the SiteName transaction details. Both Create and Delete transactions are stored in this same table. The problem here is that there is no dedicated identifier column which can tell whether a given SiteGroup-SiteName combination is currently active (i.e. not yet been deleted)
SiteName is always unique and no 2 active SiteNames can have same name UNLESS a given SiteName has been previously deleted. 'TestSite2' in above table example.
RequirementThe requirement as mentioned above is to get a list of active only SiteGroup-SiteName combination which have not been deleted yet.
Only way to do so is to check if any SiteGroup-SiteName combination has a Delete transaction type value or not and compare the TransactionTime.
The correct output for above sample table should be as follows since only TestSite3 after once created has not been deleted (hence it's considered to be active):

QUESTION
I'm a macro newbie and I'm just making a simple macro program using a nested for loop and an excel table. I have attached my code here.
What I want is when I input P,Q, and SGF values, I want to see results for each loop indices in row wise in "Table4". (My table has four columns and they should be displyed a,b,Y and (SGF-Y) values.) But this code only creates a one new row and shows results of the last loop value. (When a=10 and b=10) But I actually need 100 results. Hope you understand my question. Thank you!

QUESTION
I have a setup like this.
Application Load Balancer(internet facing) LB1 with entry in Route 53 as loadbalancer1.com
LB1 is in security group sg1 which has inbound rule to accept all Https requests.
LB1 has target group attached which has an EC2 instance instance1 which belongs to security group sg2
sg2 has inbound rule which specifies traffic can only come from sg1
I have another EC2 instance instance2 in Security Group sg3. This instance wants to access instance1. It does this by calling the load balancer loadbalancer1.com(on port 443 i.e Https)
This setup works. Now I want to make an improvement. Since loadbalancer1.com will only be accessed from instance2. I want to change inbound rules of security group sg1 to accept traffic only from security group sg3. If I do this, loadbalancer1.com is no more reachable from instance2.
Any idea why?
...ANSWER
Answered 2021-Aug-02 at 21:34It's a very good question. TL;DR: it only works for internal traffic that doesn't leave the VPC.
Here is what's going on in more detail:When the instance2 accesses the internet-facing load balancer, the traffic first leaves your VPC and goes to the public internet. Then the traffic reaches the ELB through some network routings, and the ELB forwards the traffic to the instance1.
When the traffic leaves the AWS VPC and re-enters it, the source SG metadata associated with the traffic is "gone". From the SG of the ELB point of view, it only knows that the traffic is originated from the public IP address of instance2.
According to the Security group rules documentation:
When you specify a security group as the source or destination for a rule, the rule affects all instances that are associated with the security group. Incoming traffic is allowed based on the private IP addresses of the instances that are associated with the source security group (and not the public IP or Elastic IP addresses).

QUESTION
I got a dictionary of dataframes ,dataframes
, which are time based profiles with values x
and y
for each point in time. The following shows the dictionary and one dataframe of this dictionary
dataframes={'SG1':Dataframe, 'SG2':Dataframe, 'SG3':Dataframe, 'SG4':Dataframe, 'SG5':Dataframe}
With those I want to create a dictionary of new dataframes; dataframes2
, where the values x
and y
are a sum of the old dataframes multiplied with a value.
This value is contained in another nested dictionary:
base_dict={'area1':{'SG1':0.0,'SG2':1.0}, 'area2':{'SG1':1.0,'SG2':0.0}}
( note: I shorted the dictionary)
At the end dataframes2
should look like this:
dataframes2
={'area1':Dataframe, 'area2':Dataframe}

Answered 2021-Mar-17 at 10:41If all your data frames have the same dates and times, you can do it in one for loop, iterating over keys and values of base_dict
