Rs what does ping mean

For descriptions of the information displayed by rs. The rs. Replication lag is a delay between an operation on the primary and the application of that operation from the oplog to the secondary.

Replication lag can be a significant issue and can seriously affect MongoDB replica set deployments. Excessive replication lag makes "lagged" members ineligible to quickly become primary and increases the possibility that distributed read operations will be inconsistent.

In a mongosh session that is connected to the primary, call the rs. Returns the syncedTo value for each member, which shows the time when the last oplog entry was written to the secondary, as shown in the following example:. A delayed member may show as 0 seconds behind the primary when the inactivity period on the primary is greater than the members[n].

Check the network routes between the members of your set to ensure that there is no packet loss or network routing issue. Use tools including ping to test latency between set members and traceroute to expose the routing of packets network endpoints. If the file system and disk device on the secondary is unable to flush data to disk as quickly as the primary, then the secondary will have difficulty keeping state. Disk-related issues are incredibly prevalent on multi-tenant systems, including virtualized instances, and can be transient if the system accesses disk devices over an IP network as is the case with Amazon's EBS system.

Use system-level tools to assess disk status, including iostat or vmstat. In some cases, long-running operations on the primary can block replication on secondaries. For best results, configure write concern to require confirmation of replication to secondaries. This prevents write operations from returning if replication cannot keep up with the write load.

Mike Muus coined this tool name from the sound that the sonar makes because its methodology is similar to the echolocation of sonar. There are several issues that concern many users. If the destination host is unreachable, the user must modify the local route table or switch the node on.

If the host is unknown, the user must verify the name and availability of the domain name system DNS servers. If the request times out, the user must increase the waiting time by using the PING. Furthermore, the security risk is also a concern, to solve this, there are several systems that allow disabling the reply despite the fact that there is a mandate to always send a reply.

Ping Packet Internet Groper, commonly abbreviated as PING, is a diagnostic tool that tests connectivity between two nodes or devices across a network. Resources Wiki.

You need to enter the correct confirmation code which has been sent via SMS. For Android users, the OTP is automatically populated on the screen. Alternatively, in case of any problem you can also request to resend OTP after one minute. You can simply reconnect to Ping Pay and verify your transaction history to check if the transaction has been executed.

On most handsets, you can answer the call or read the SMS while Ping Pay continues to run in the background. After you have finished your call, you can resume the application. However, for certain handsets, you may need to re-open the application and login again.

In case the call is extended for a longer duration then the application will get logged out and you will have to login again. Yes, as long as you have GPRS activated on your mobile number, subject to availability of the network, you can access Ping Pay anywhere in the country.

Please keep in mind that you might be charged special roaming rates for using GPRS. However, the appearance may differ slightly based on the mobile phone and its display interface. In this case your Ping Pay account is locked, you will have to register to the application again. Yes, once registered you can use either of the details, Internet Banking or Debit Card details while registering again.

In case you change your handset, you need to download the application again and register to it. The application on the previous device will be de-registered. In case you change your mobile number and you are an Axis Bank customer, please register it through Axis Bank ATM or Branch and then install the application for the new number else the "Send Money" functionality will not be available.

In case you want to use the same number to use the application again, you will have to download and register to the application again. You will not be able to re-register for 24 hours after locking the application. You will have to download the application again from the Play Store or App Store and register for it. A non-Axis Bank customer can link an account for receiving money.

However sending money option will not be available to you. Ping Pay is only available to retail Savings Account customers of axis Bank. Hence, you will be able to view the balance of only your savings account. All the savings accounts linked to the Customer Id will be reflected and you can choose a default for all future transactions. The same can be changed in manage accounts. The mongod only removes an oplog entry if : The oplog has reached the maximum configured size , and The oplog entry is older than the configured number of hours based on the host system clock.

To configure the minimum oplog retention period when starting the mongod , either:. Add the storage. To configure the minimum oplog retention period on a running mongod , use replSetResizeOplog. Setting the minimum oplog retention period while the mongod is running overrides any values set on startup. You must update the value of the corresponding configuration file setting or command line option to persist those changes through a server restart.

If you can predict your replica set's workload to resemble one of the following patterns, then you might want to create an oplog that is larger than the default. Conversely, if your application predominantly performs reads with a minimal amount of write operations, a smaller oplog may be sufficient. The oplog must translate multi-updates into individual operations in order to maintain idempotency.

This can use a great deal of oplog space without a corresponding increase in data size or disk use. If you delete roughly the same amount of data as you insert, the database will not grow significantly in disk use, but the size of the operation log can be quite large.

If a significant portion of the workload is updates that do not increase the size of the documents, the database records a large number of operations but does not change the quantity of data on disk.
