# Troubleshooting

**When I tried using the Edge browser, the filters are not clearly visible when viewing data?**\
 Make sure you have proper screen resolution to get the filters displayed.

**Accessing RDA in firefox is working okay but chrome is giving this error** `NET::ERR_CERT_INVALID`**?**

* Right click, select inspect element
* click on console tab
* Copy paste `sendCommand(SecurityInterstitialCommandId.CMD_PROCEED)` press Enter
* Boom! it should load the page :)

For other solutions refer to this [page](https://stackoverflow.com/questions/58802767/no-proceed-anyway-option-on-neterr-cert-invalid-in-chrome-on-macos) to fix this issue on Chrome browser

**Not able to access RDA UI?**\
Make sure your docker service is up and running.\
Note: On Mac OS/Windows, check your desktop docker is up and running (docker icon will show up on)

**Why the following pipeline is failing at @dm: eval?**

```
%% stream = no and limit = 0
#snow:incidents     
-->  *dm:filter        number = 'INC0012366'
-->  @dm:save    name='temp-snow-incident'
-->  @c:new-block   
-->  @dm:recall    name='temp-snow-incident'
-->  @dm:map    from='description' & to='data'
-->  @dm:eval    subject='help.please'
-->  @nats:requests
```

dm: eval expects a proper valid expression. Add the following to @dm: eval to fix this.

`--> @dm:eval subject =`` `**`“‘help.please’”`**

#### Is there any way to export the output of bots() command into a CSV file or a dataset

Use  the following ( get\_bots() will return it as a data frame)

```
get_bots().to_csv('bots.csv')
```

 

**I want to pass `content-Type` as a header in the params for the rest-client bot, but I get a cfxql error:**

Use backquotes with cfxql   `` `Content-Type ``\`   (- is a special char for cfxql )

#### How to use extract FQDN from a string or a summary data?

Use grok exprssion to extract FQDN from a string or from summary data as shown in below example:

```
@c:new-block     
-->  @dm:empty    
-->  @dm:addrow summary='Device Performance for cfx-web01.engr.cloudfabrix.com 10.95.131.22 '
-->  @dm:grok column='summary' and pattern='%{(?i)([a-zA-Z0-9]+(-[a-zA-Z0-9]+)*\.)+[a-z]{2,}:fqdn}'
-->  @dm:grok column='summary' and pattern='%{IPV4:vm_ip_address}'

```

**I want to use grok in my pipelines, where can I get some examples?**

Below are pipeline code snippets that provide examples of how to use grok.

```
####
# Example -1 -- Extracting IP and port using pattern
####
@dm:empty
--> @dm:addrow description = "Server ip is 10.23.1.245 and port is 2345"
--> @dm:grok column = "description" & pattern = "Server ip is %{IP:server_ip} and port is %{INT:server_port}"

#####
#Example -2 
#####
@dm:empty
--> @dm:addrow instance = "SOME TEXT 10.1.2.5:8080"
--> @dm:extract columns = "instance" and expr = ".* (?P<ip_only>[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}).*"

#####
#Example -3 
#####
dm:empty
--> @dm:addrow instance = "SOME TEXT 10.1.2.5:8080"
--> @dm:grok column = "instance" and pattern = "%{IP:ip_address}:%{POSINT:port}?"

```
